    I don’t hear this being the bass player, as it is already starting, it sounds more like something is being selected/switched on in the studio, or going into standby.

    The Front End Digital Foundation

    Well I compared the Audioquest Vodka against the AQVox's top of the line, “Edge" Ethernet cable.

    Both are great RJ45s, but I have now replaced the Edge with the Audioquest Vodka between the GigaFoil v4 and Aurender N10 and, I am BLOWN AWAY. The Vodka dropped the noise floor; zero loss in sound quality and gaining several points on the score board. Honestly, I was torn to pull the Nordost Heimdall out the configuration, and repurpose to modems and routers, but it was a solid move, and I think this is helping get more from Vodka than I recall from past use.

    I am hoping my 15M Ghent Ethernet cable comes tomorrow, it showed clearing customs in Los Angeles last night. This will span the distance between switch and optical replacing a utility grade Cat 6 and then tell us if Gigafoil has any benefit in sound quality with a better cable going into it.

    I can tell you based on my experience, use the best cable coming out of the Gigafoil V4 makes a considerable difference.

    Happy Listening!

    Update 4.057.

    Since it was recommended to use a lesser quality cable into Gigafoil and a high quality out of Gigafoil, I played along but consciously I could not leave well enough alone.

    I ordered and received my new 15M Ghent made Ethernet cable to replace the generic Cat6 between the AQVox SE switch and the Gigafoil -

    Took me a bit to run this long of a cable, and made my son help feed cable as we routed this right at 50’ to my music room.

    The Ethernet Cable is budget friendly, very well made, as all of the DC cables I received from Ghent - I highly recommend him and he does do Fiber as well. Here’s the specs

    (Belden 1303E CatSnake Ethernet Cable with JSSG360 Dual-shielding protection, especially designed for Audio quality
    Purely handmade craftwork, genuine material and solid substance

    Cable: Belden 1303E CAT6A CatSnake Cable, support 10GBase-T, 1000Base-T, 100 Base-T...
    Connector: Metz Connect CAT6A fully shielded plug (made in Germany), support 10GBase-T)

    The cable will take some time to settle in, but after connecting I could hear more openness with a natural sense of timbre and resolution at the onset, things appear to be a bit louder, this cable will break in nicely.

    So right now I am not doubting the incoming cable to Gigafoil does matter - I’ll confirm this over the weekend and report.

    In a different battle of the Streaming War things were sounding excellent before the Ghent 15M Ethernet arrived as I did replace the Audioquest Vodka with an Audioquest Diamond from the Gigafoil to the Aurender. I highly recommended these two lines from Audioquest, with Diamond just giving you more of Vodka but for many may not be worth the cost, and that’s ok, Vodka is no slouch.

    I’m toying with repurposing the Vodkas back in place of the Heimdells at the Modem and Router, as Vodka is wrapped in solid silver and may fit better with Diamond and I’m also thinking about pulling the AQVox SE and replacing this with the SOtM switch with the Silver wired upgrade package and a SOtM 500 Linear Power Supply, and maybe sell a Keces P8, and a couple of Nordost Heimdell 2 Ethernet cables then I’m sticking a fork in it, and enjoy the music for Summer.

    The Front End Digital Foundation

    Hello Everyone!

    Following up on my reporting; here’s what I did in my last stages of configuration.

    Prior:

    P8 > Arris Modem - 12v > Heimdell 2 > Eeros Router > Heimdell 2 > AQ Vox SE - SMPS > Belden 1303 Catsnake Cat 6/Ghent 15M > Gigafoil > AQ Diamond > Aurender N10

    Current:

    P8 > Arris Modem 12v > AQ Diamond > Eeros Router > AQ Vodka > AQ Vox SE > Belden 1303 Catsnake Cat 6/Ghent 15M > Gigafoil > AQ Vodka > Aurender N10

    Here’s what I’ve learned on how my system responded to the changes;

    - Placing the AQ Diamond from the modem to the router and using AQ Vodka from the router to the AQVox SE switch brought a greater sense of overall sound. Darkness was enhanced, a very natural timbre embodied the instruments, benefitting high, mid and low range. Adding Vodka from Gigafoil to the Aurender N10 sealed the deal!

    - A better grade cable between the switch and Gigafoil brought the effects mentioned above improved in a similar manner just at a step below, and for clarity it was not subtle.

    - Connecting three other rooms direct from the home network to the AQVox SE to the switch with the cable setup increased picture clarity and benefited the sound at a crazy level.

    - The AQ Diamond and Vodka loom out performed my Nordost Heimdell 2’s, I’m not repurposing them elsewhere, they will be posted for sale. Note: Nordost are excellent, but I’m going SOtM and between AQ and the SOtM options having optional silver cable in the build and their DC cables will be I believe will be a better match.

    - I noticed cables need a bit of settling when moving burned in chords around in your system, time depends on each application but in a much shorter window.

    Future upgrade paths:

    - Dedicated Circuit in mechanical room for modem and switch.

    - SOtM switch with clock and modified cabling and SOtM LPS

    - AQ Diamond cables between router and switch and Gigafoil to N10

    Re: The Front End Digital Foundation

    Great work.

    I've been addressing the front end as well with a dedicated line in the utility room and a Topaz iso transformer before the Att supplied Arris Modem/Router.

    Speaking of Modems, I'm curious if anyone has looked into modifying stock modems into more audio friendly components? All the attention seems to be on the Switch.

    I'm also curious to hear about the Ghent/Belden lan cable. I have a 75' cable buried in conduit from the modem to my studio that I could replace if economical. I may check to see if Ghent makes an outdoor version.

    And, if you or anyone needs a longer AQ Diamond, I have an 8m that I can sell at a great price.

    Hi

    Cool on the dedicated

    Not familiar with anyone doing aftermarket modems

    For what I’m using the Ghent for, it proved itself and it will stay serving its purpose.

    I would see if somehow you can keep the AQ Diamond, unless your dead fast set to sell it.

    Re: The Front End Digital Foundation

    I definitely plan to keep using the AQ diamond, I just don’t need an 8m length anymore.

    Doesn’t it seem odd that apparently no one is working on a modification to the modem/router? I’m guessing they are a major noise generator.

    Understood on Diamond

    Yes, it seems odd and maybe someone is or will. It would benefit both Audio and Video, and maybe the Video guys will take the lead?

    In the interim, keeping the Mainz power to the distribution the best as possible for the linear power supply that powers the modem with decent cables has been my offense in gaining forward momentum.

    The Front End Digital Foundation

    Grounding is Performance!

    I moved my AQVox SE switch out of music room into my mechanical room when I redid my front end, and when I did that, I lost the benefit of the passive grounding connection from the Nordost QKore 6, or so I thought.

    All was not lost, the AQVox SE has a grounding terminal on the power side of the switch. Lucky for me, right behind the switch is the connection box for cable coming into the home, and this includes a grounding cable and connection coming from the outside.

    I went to Home Depot and purchased 2’ of 6 gauge solid Copper for $1.40. The plan was to create two loops and screw it in to both the switch and the grounding post in the connection box.

    On the drive home I thought to myself there was no way the screw had enough thread to wrap around 6 gauge, and I was right. Then it hit me, copper is soft, so hammer down each end flat, drill two holes and mount - it worked, and boy did it!

    Prior, KingRex ran a grounding line from the sub panel to great effect, but there was a slight hum on the Aurender N10 that you had to get close to hear, it’s now gone. The tweeter and mid’s on the Wilson Alexias emitted a faint electrical noise where again you had to get up close to it to hear, it’s now gone. My system is quiet from stem to stern.

    What’s odd is even music stored on the Aurender hard drive even sounds significantly better.

    I’m hearing black, meaning no noise. Instruments and vocals sound open, smooth and simply amazing and more parts embedded are coming out and clearly pronounced. I always use a handful of songs to critique what I am listening for.

    The takeaway:

    - Addressing grounding from outside the dedicated circuit is equally as important, meaning network gear.
    - As good as the AQVox SE switch is, noise still gets to the switch whether it’s in the line, caused upstream by the modem and router or the switch itself.
    - If you have a grounding screw on your switch seriously consider using it!
    - I have lost nothing in sound quality, everything now is sounding better than when the switch was connected to QKore 6, I mean night and day.

    If I was better at fabricating or perhaps more patient I could have made the flattened terminations more professional. The one in the cabinet in particular but it will never see the light of day, so FK it, I’m done!

    Re: The Front End Digital Foundation

    I put my new/used HD Plex power supply on my Router and Modem. I already have a Linear Solution switch with a linear PS. I have all Blue Jeans Ethernet cables. Ed is right. Big change. Big !!!! Much more bass. More clarity as heard by more natural instrument tones. It benefitted everything. Not just the streamed or stored in my NAS. The music stored in my Mojo Audio server usb connected to my Mojo Audio dac also sounds significantly better. I guess it goes to show, injected noise from any source brings the whole of the system down. I'm glad Ed got me excited to go this route.

    Glad to hear Rex, it’s these little things and really doesn’t matter if your streaming, spinning discs or playing albums - it turns a system into more for little cost especially in comparison.

    The Front End Digital Foundation

    After I hooked up the 6 gauge copper wire from the switch to the cable junction box I noticed the grounding cable for the cable and phone was attached to the incoming water pipe on a Copper line - the home is all Copper, no Pex.

    Last night I tied into the clamp and heard a difference but was not thinking as good as when it was in the cable box, there was now 4 pieces of wire in the existing clamp at different diameters, plus some were stranded, others solid - then I did some reading after the fact and realized it was said not to tie in with cable and phone because their issues could become mine.

    So I bought two new grounding clamps, keeping the 6 gauge audio separate, then cleaned the pipe and was cautious when placing the audio clamp onto the pipe as the elbow is about an inch off and don’t want to break soder.

    Let me tell you the difference was now greater then the cable box tie in, and I had a hunch this was gonna happen.

    That little noisy AQVox SE switch needs to be tamed and begs for grounding, and that’s what I gave her The Front End Digital Foundation My system is killing it as it should for that pile of cash sunken into it, and it every TV and Streamer in the home has taken a step up as well.

    So if your not using linear on the switch, and your switch has a grounding screw then consider following something like I did as an option, I now have under $20.00 in this and the work was simple at best.

    Re: The Front End Digital Foundation

    I received via Amazon the iFi Groundhog Spade Connector as Puma Cat suggested and connected this to the AQVox SE, the same switch I just hooked up 6 gauge copper to.

    Once again the system is impacted, but I need more time to assess the results. What I did notice is while the Aurender now is as silent as a lamb, I need my PreAmp at 50% to get the same result before at 40%, but there is no fatigue and the detail and openness is there on high, mid and low frequencies. So I find it odd I need more power if noise is being removed from the line, I would think the opposite would happen like I’m hearing in my bedroom system. I will look at my gain adjustment on my DAC which is at 70%, and maybe it needs to go up 1 or 2 clicks.

    I do believe noise travels through other components via interconnects, cables etc and to get the most out of your system the electrical foundation needs to be squared away, and you can tune your system with cables, their configurement, isolation and everything under the sun.

    I also found out the SMPS was the culprit that affected the server and PreAmp with noise, and this makes sense as the plug has no ground.

    I also believe every action has a reaction, meaning you can overdo things and either need to correct for it or remove it and sometimes it’s best to leave well enough alone.

    So just when I thought I was out, I’m pulled back in The Front End Digital Foundation

    The Front End Digital Foundation

    Hello Sharks:

    Added the iFi with Spade to the AQVox SE switch using the repurposed Nordost Red Dawn power cable formerly feeding the Keces P8 and replacing it with an AudioQuest Thunder Source power cable to the P8.

    The iFi spade contributed a modest gain to noise reduction, and wanted to be sure I wasn’t losing anything as I was suspicious. I believe the Red Dawn did something here, but not sure as the Thunder was put in and the first hour you could hear where things might go, then the burn in on the Thunder set in, making me shut the amps off and let the cable do it’s thing over night. The next morning was a night and day difference, Thunder is bringing things together nicely.

    Takeaway;

    - iFi proved a modest gain in conjunction with my 6 gauge solid copper passive addition, a better cable may make a difference but not sure - the iFi grounding process uses electrical grounding whereas my 6 gauge switch grounding is what I consider passive

    - power cables influence Linear Power Supplies, and the Keces in my system performed horribly with an Ansuz C2, good with a Audioquest NRG 2, better with a Nordost Red Dawn and well on its way with the Audioquest Thunder Source passing all.

    - Pay attention to what’s coming into your system as you can rob performance from other pieces in your system.

    - Grounding; electrical and passive makes a good system into a great system!

    Happy Listening!

    Great information, Ed. I can’t imagine going through the detailed A/B testing you’re going through.
    For instance, trying 4 different power cables feeding your power supply!
    One question: Are you using a separate grounding from your switch in addition to the Keces
    lpsu? I thought the LPS would negate the need for additional grounding?

    Re: The Front End Digital Foundation

    Hey there -

    The Keces only powers the modem and a router. The AQ Vox SE uses its own SMPS switch that the manufacture indicates not to change as it has been tuned, even using after market ones they even sell. I tried changing this to a LPS and AQ proved to be right, at least in my case.

    So the AQ VOX SE has the 6 gauge passive copper grounding i made up (major step forward) and the iFi current grounding (minor step forward) plugs into the Nordost Red Dawn power Cable which plugged into the Keces - just not 100% sure what the Red Dawn power cable did but think it added something but that is a “think" statement. Now the Thunder Source into the Keces P8, it was another major step forward, no “thinking" there, it was a "know"

    Happy listening!

    For instance, trying 4 different power cables feeding your power supply!
    One question: Are you using a separate grounding from your switch in addition to the Keces
    lpsu? I thought the LPS would negate the need for additional grounding?
    The LPS may be passing high-impedance leakage currents, this is what the fix that UltraFast has ameliorated using the iFi Groundhog spade connector going to ground.

    Puma, Something kept bugging me on the iFi, the modest gain was there, but I was losing sound - an oxymoron. I first powered iFi with the OEM Keces power cable, then switched to Nordost Red Dawn, thinking maybe Red Dawn may of been too much, so back to the OEM to no avail, leading to pulling it from service and Amazoning it back.

    You may laugh, but I like playing specific songs when critical listening, one of them is Madonna’s Vogue. This song is recorded in Q Sound where the phase is adjusted and it gives a surround illusion - my system kills this in a good way, blowing away all guests. I literally was losing the virtual percussion tapping on the far right side of me, all other songs were prevalent as well.

    This may work good for others, just not in my application.

    Quick path update.

    P8 > Arris Modem 12v > AQ Diamond > Eeros Router > AQ Diamond > AQ Vox SE > 15M Belden 1303 Catsnake Cat 6/Ghent > P3 > Gigafoil > AQ Diamond > Aurender N10

    Note: Two other A/V home systems are also connected to the AQVoxSE bringing awesome results in sound and in picture quality - running all similar cable has its benefits, the Diamonds are killing it!

    Then I went from the AQVox SE > AQ Vodka > to a cheap Netgear switch powered by LPS.

    There are a few cameras and the video game room on this switch.

    Honestly I could care less about this path, but then I ran a second 6 gauge solid copper grounding cable and the difference was not subtle, and now I’m talking the whole enchilada. What’s the whole enchilada? I mean everything in the house that is connected with Cat 5/6.

    I may be off but I’m thinking plugging into the Netgear from the AQVox SE provided the benefits stated up in my previous comments, but the signals are going both ways bringing back noise contamination to the AQVox SE for a lack of better term, and component grounding the Netgear out despite receiving electrical ground from the LPS closed yet another loop.

    The audio background became darker than dark, no loss to detail or sound quality on the 2 channel and all the TV blacks are blacker and other colors sharper.

    This does not even make sense, but I can clearly hear and see the difference and not I’m imagining or wanting change, and there are no drugs or drink used in this experiment, conducted strictly out of being curious.

    Takeaway:

    As I said before run a 6 gauge copper grounding wire to your switch, flatten one end using a press or simply beat it with a hammer and drill a hole assuming the switch has a grounding port. Run it to the main water pipe and connect with a brass connecting clamp (both available at a hardware store) unless you can get outdoors to a rod in earth - so easy to do, and for those that are not clear this is passive, so it’s not running with hot and neutral wire, two different types of ground.

    Cost is less than a dollar per foot, the return is at 100 times, you can also use less gauge but not sure the quality path you will get.

    And remember, for those of you that are half assed tinkerers like me, you get the self satisfaction of the Hobby part of this crazy thing we call Audio!

    Enjoy Your Sound, Enjoy Summer!

    Re: The Front End Digital Foundation

    Never compared. But I definitely hear an improvement with the HDplex on my router and modem. They make a difference.
    Right now its only on one. I forget which. I was having drop outs. Not sure why. Could have been the utility. All was fine on both for a week. Could be I was maxing out the 100 watt PS. I might go back to both and see.

    Re: The Front End Digital Foundation

    For a few months, I used a Keces P3 to power the Att Arris Modem. (And a Topaz iso transformer was in front of the Keces)

    A few weeks ago, the modem went bad. An Att tech deduced that the Keces killed it and charged me for a new modem and service call.
    Reason given: "wrong amperage for the modem."

    I was out of town at the time, but having just returned, I see that the Keces output is 3 amp and does in fact match the 3 amp input of the modem.

    I'm going to challenge Att on this, but just wondering if I could be overlooking anything beyond the obvious?

    Sounds like ATT is trying to place the blame on someone else. No issues here.

    Re: The Front End Digital Foundation

    I don't believe the Keces power supply had anything to do with the failure of the modem. Modems and routers fail all the time. Especially a combination modem router. They have too much to do and they just can't handle it.
    '
    Legally it's a completely different story. You have altered the power supply and that alone would negate any implied warranties.

    I don't know how a Keces is design, but I gather switch mode power supplies always output a constant "voltage". I have heard linear power supplies voltage can swing based upon the load. I don't think that is a problem with keces. I believe it is a regulated voltage but who knows, there could be something to that.

    That’s what I was afraid of. That Att can just say you put an unauthorized power supply in front of our modem whether or not it meets specs.

    Something tells me I’m in for a lot of frustration if I try to fight them on this...

    Bullshit. They can handle their function just fine without being overloaded processor or logic wise.

    More likely, is a brown out condition or multiple brown outs in the A/C feed (ala storm activity) that killed the AT&T device.

    Here is what the P8 is doing, the higher amperage is the modem, the lesser, the switch both running 12V and together about 1.1 amp.

    I disagree. When mine went bad I had a local computer tech company inspect my system and they told me what I relayed here. Mine started as intermittent dropping out that became so bad I finally could not connect. It was not a total failure, loss of power, wont start. They very much said a Combo modem and router is to much processing demand. They suggested I go with separates. When I did I also realized a nice bump in sound quality that was validated by a few other industry members on Audionirvana. Separated that is sound better than a combo unit.

    I agree a true brown out can cause the unit to heat up and fail. Small spikes maybe. A lightning strike yes definitely. It is my belief my 75 ohm isolator that was destroyed in our last lightning storm may have saved some of my gear. I should have remembered to disconnect my Ethernet. I guess I got lucky.

    Re: The Front End Digital Foundation

    Nice image Ed. I forgot it has a display that shows the voltage. If I was Wilco I would at least send a letter with the spec and state the long time customer crap and see where it goes. I usually get my way with internet providers. Personally I would sxxxcan their modem and get my own. I like the Surfboard I have. Tell them to take the monthly fee for the one they provide and shove it somewhere. Anytime you start taking monthly revenue from them they listen.

    Re: The Front End Digital Foundation

    I've had four of those combo units go bad including one right out of the box in just over five years. Only one could be attributed to a surge when they were getting the power back on after Hurricane Michael. The other two just started slowing down noticeably over time and I had Xfinity come replace them before they quit altogether.

    Re: The Front End Digital Foundation

    Unfortunately, the images with Mercedes and Porsche by the modem may be too much for this site

    I have a stand alone modem, the Arris Surfboard, 8200 or 8800, that supports 10/100/1000 and it cost somewhere around $120?

    I agree, it made more sense to go my way and buy my own.

    Re: The Front End Digital Foundation

    According to my neighbor's son who is a service manager they got a bad batch from Arris when Arris switched their manufacturing in China to a different plant. I just learned to run Speedtest every couple of weeks and when I noticed the drop in speed start put in a service call. Takes about 15 minutes to swap them out as they have to be connected to the main network. You can either do it yourself or let them do it. Takes the same amount of time using the IOS app. It seems those have all been used up by now. The one after Michael was as the result of the multiple stutter starts they had trying to get the power to stay on at first.

    The Front End Digital Foundation

    Interesting perspective guys. I am unaware of so many failures (hardware related) in the most recent consumer grade products and in particular, the Xfinity units of which it seems there may have been a bad batch.

    Too bad the consumer grade products are not always code upgradable. Then again they can be had for little money when it's time to replace.

    For the record I am not a proponent of a combo modem/router either and I've always had separate modem and router here.

    Apologies for calling bs...

    Looks like UpTone is close to launch of this new Ethernet switch that appears to change a lot of things we thought we know,

    I know someone who will go crazy over this and probably will have to write a review, Stephen time to wake the Cat!

    Re: The Front End Digital Foundation

    I agree. My whole system has taken a step forward with the most basic ADD-Power components. I have a much more resolving system now. There was a lot more grunge distorting my playback than I realize. The fatigue has significantly dropped with these components. What I am now finding is the isolation components under each piece of equipment are more critical now. It's taking me time to go through each device and determine what needs to be there.

What I am now finding is the isolation components under each piece of equipment are more critical now. It's taking me time to go through each device and determine what needs to be there.
    Great to hear!

    There’s no doubt it will contribute to reducing the noisy edge making SQ more natural, tranquil and enjoyable - I guess it is true, your never done!

    Re: The Front End Digital Foundation

    I lied to myself saying I was done with Digital.

    I will order UpTone Audio’s etherREGEN.

    Puma Cat Stephen talked about this earlier, and I got a note from Uptone saying ready to order and now learned this batch of 250 is sold out and a second batch, I will be on the third series January receiving list - if they can only make one more as a Christmas present.

    which ADD power components are you guys using? And I wonder how they “synergize“ with PS audio power regenerators?

    Re: The Front End Digital Foundation

    I have the 2 most basic pieces, Ed was going to put them in his utility room. I have 1 Electra Clear and 1 Symphony. I am getting a second Electraclear for my utility room.

    Ed knows way more but the owner said they work with most power conditioners. I have an Akiko Corelli. It works fine with it. Of course that is not a regenerator. The real question is, do you put it before, or after your regenerator. I bet both ways would have some affect.

    I don't think you will like it Ed, your to advanced for it. Your server and DAC have better usb components than the regenerator. Your Nyquist does not need the power over USB so the regen isn't doing much for you, Give it a few weeks before you comment, I bet it will change things. But I bet you will go back to direct connected.

    FYI. I'm not bagging on the Uptone. I hear they are more effective on a lesser dac that does not create it's own usb power. Your inserting $700 beteeen $40k. That regen would be amazing for anyone feeding a laptop, usb connected to a dac that needs the usb power run from the server.

    Hey Willco

    I recommend starting off with 1 Symphony or 1 Symphony Pro - both will contribute nice results. These both have 8’ wire antennas you simply drape over or behind cables and gives out a 10’ range.

    (While not a requirement, the Symphony has a SMPS power supply and the Symphony Pro an internal one. If you have a LPS with an extra port and power, the Symphony requires 12V at 1.67 amps or the Pro takes a C5 connector (Mickey Mouse, not Figure 8) and I bought the new Shunyata Noise reduction, not sure what it does, but the cost is reasonable, and I am a Shunyata fan.)

    Plug Electra Clear into your distribution along with Symphony or S/Pro at the reference.

    Use the second Electra Clear at the distribution feeding the modem and switch - later add a Symphony here.

    Or add two Symphony and two Electra Clear to both modem and reference

    I can help you if you PM your phone or email.
