Re: The Smith Chart and...Power Cords
This thread has been an interesting read for me. It’s truly amazing that people still think power cords have no sonic benefits. Please, I invite you to the store. We will use a single integrated amp with a built in DAC (you can pick - boulder, Soulution, Hegel, etc) and speakers of your choice and music of your choice and the only thing we will change is the one single power cord which is running everything. Stock against after market. If you still think it’s all psychosomatic, awesome. No harm no foul. But I guarantee you will be dumbfounded by the differences and sonic improvements.

Re: The Smith Chart and...Power Cords
No need, he just needs to show me an e-meter reading with that wormhole thing, measurements suddenly matter now. New age audiophile, if I can measure 0.00001% THD aka "electrical noise", its audible, period.
I wonder what recordings for the last 50 years have no noise riding for free, baked permanently in? Or does magic "rinse" them clean??
Oh well, as incomprehensible as ever...Just a moment...

Too bad the only competent "engineers" in high end audio are the cable guys, the mega buck component guys designing the power supplies in every audiophile system aren't worth a poop.

Yep, I have a TLA I personally use....MFB: Male Fighting Behavior.
FWIW, I see the same exact behavior in any internet forum that is predominantly all-male: sports cars, sport bikes, digital cameras, as well as audio. Doesn't matter what the "subject" or topic is, I see the same exact behavior. By contrast, you never see women behaving this way on-line.Ĥѱ = 𝐸ѱ

Re: The Smith Chart and...Power Cords
I'd be there in a flash were it not for the thousands of miles between us. The cable and other similar audiophile tweak demos I've seen at audio shows have been generally underwhelming to the extent they have a tinge of the "The Emperor's New Clothes" about them, with many attendees ruefully nodding in recognition of the "massive sound improvement" - yet keeping their hands firmly in their pockets.
Perhaps I should be more open-minded and ask a local dealer to do his best to convince me one way or the other.Sources - NAD M50.2 (streamer, CD player, CD ripper, hard drive music store)

Re: The Smith Chart and...Power Cords
You are welcome. Yeah, no issues, it's a personal choice as I said. But let it also be known that Shunyata are also advertising recording studios using their cords and conditioners (thank God!), as well their successful applications in the medical field. Perhaps you've read about the cardiologist who tried one of his high-end Shunyata NR cords on the EKG machine in his hospital and was blown away by the clarity of the traces, which eventually then led Shunyata to launch a subsidiary company focused on reducing noise in medical devices? It's called Clear Image Scientific Technology – Clear Image Scientific and if you visit that page, you'll see a better demonstration of the same Entech device plus their specialized cords (also notice the AM-radio conversations picked up by the Entech).
Regarding power supplies in our equipment, roughly a decade ago, I was discussing with an audiophile the exact same thing: why do they need noise treatments. My answer was, they wouldn't if they were the size of refrigerators - not practical, obviously, in high-end applications and apparently medical as well. Then, about five years ago, I was introduced to a retired electrical engineer, also an audiophile, who apparently worked for the Air Force if I recall correctly. He pointed me to a video aboard a military aircraft, and specifically to one of the power supplies he designed for a device on that reconnaissance plane as captured by the video camera, and guess what, that power supply was the size of a medium-size refrigerator. He said it was exceptionally complex and very clean. So it's not that competent electrical engineers cannot design such power supplies for audio, they obviously don't, save for a few exceptions like the mega Pass monos with external power supplies.

Re: The Smith Chart and...Power Cords
So if PCs do nothing, why are the naysayers not just using Black and Red ICs and Zip Cord for Speaker wires as they can't possibly make a difference either?
I noticed HH has exotic cables to his horns and AJ uses some boutique cables in the pics on his site. They must do something more than please themselves visually....or maybe not.-----------------

Re: The Smith Chart and...Power Cords
Since you are sure these small companies are overcharging you, and in your previous post you talk about your understanding of economics 101, please share with us the small cable company of your choice, their:
NET PROFIT from their operations that shows they could afford to charge less and still have the ability to cover general business admin, R&D, rent, paying for shows and marketing, inventory, shipping, taxes, healthcare and insurance AND be able to pay for the upcoming year.
Please, since you are so convinced their prices are wrong and too high, show us how they can successfully run the business charging less. Your feelings don't count - just the hard factual numbers please.
Share with us what their actual salaries are as well to show they are "raking it in" while "sticking it to us audio peeps" as you are implying.
Only factual numbers please otherwise admit you have no clue that they can charge less - and still survive as you stated. I'm also curios how many small businesses you've started from scratch, run and been responsible for making the payroll for employees where you are able to intelligently talk about this vs your feelings of what can and can't happen.
It's always fun to watch people with zero real world experience sit back and lecture what other companies should be charging.
I'm sure Mike could add to this with people blaming him for the cost of the gear he sells and thinking he "rakes it in" while they have ZERO clue about reality of business because clear you your post and belief takes aim at Mike as well."We are all billionaires because of the huge piles sweet dough rolling in from our participation in the ongoing campaign to suck your collective brains through a stirrer-straw." - PTA Editorial Staff

Re: The Smith Chart and...Power Cords
The difference between power cables (please let's not call them PCs as this can be Personal Computers or Power Conditioners or other PC things!) and interconnects and speakers cables is that the latter carry the signal and this needs very careful handling and nothing must be added or taken away from the pure signal. Power cords simply deliver a voltage to the power supply - nothing to do with the precious signal.
Regarding your second point, do you consider Duelund speaker cables as "boutique"? I consider them as perfectly adequate for the job and nothing more exotic is needed. I also have Cabledyne solid silver ones too but don't use them as the Duelund are just as good and much easier to keep out of sight.Sources - NAD M50.2 (streamer, CD player, CD ripper, hard drive music store)

Re: The Smith Chart and...Power Cords
Has anyone here claimed that power cables do nothing? Certainly I haven't and as previously stated have upgraded from standard cheap cables to ones made from first-class Belden screened cable. I've not heard any properly argued case for further expenditure on these simple and non-signal-carrying cables that are there to supply the power supply with whatever voltage it needs.
Power cables (let’s not call them PCs as this could be personal computers, power conditioners, or anything else PC!) differ from interconnects and speaker cables because the latter handle the precious signal that must be preserved with nothing added or taken away from start to finish. Power cables simply deliver the voltage needed by the power supply within the amp.
Regarding your second point, do you consider Duelund speaker cables as “boutique”? I have more exotic solid silver Cabledyne ones but they sound no better and Duelund can be much more easily kept out of sight.
PS - I hope you're enjoying this playful banter as much as me. None of us here is likely to change our views, but the Shunyatas of this world stay in business to keep those with deep pockets happy and satisfied that they can't spend any more than they have. Don't forget the $1000 fuses though!

Re: The Smith Chart and...Power Cords
Maybe clarify what you consider the actual amp. Because I plug my power cord One end into the wall the other into the amp, so I'm wondering how my amp isn't seeing the full 110v or so. As the power supply is the heart of any amp I would think you'd consider it part of the amp.
As I stated in a prior post you need to quit, LOL

Re: The Smith Chart and...Power Cords
In order to keep things neat, the Duelund 12 gauge speaker cable and the Belden screened power cable for the AG's amps are enclosed in a cable-tidy sleeve. Nothing fancy but exceptionally good speaker cable and perfect (for its job) power cord. If I decide to feed the AG's amp with XLR cable, this could be accommodated too screened of course.

Re: The Smith Chart and...Power Cords
No, the amplifier, being a circuit to amplify the incoming signal, doesn't need an AC voltage. Most (not all) amplifiers share an enclosure with a power supply that does nothing but convert the high AC voltage to the low one that the amplifier needs. Some amps have external power supplies and some use batteries, thus avoiding the need for a high voltage power supply, transformer, etc in the amplifier enclosure.

Re: The Smith Chart and...Power Cords
Yes, it's another subject that gets some people hot and bothered, but there are high voltage cables (normally unscreened) inside a DAC or amp enclosure and these people don't seem to get overly concerned over these, do they?
In fact both my speaker cable and the power cable are screened, so I have no concerns whatsoever, despite my speakers being 107 dB and care needs to be taken to avoid the slightest hint of noise.
Neither do I concern myself that these cables are in contact with the floor (heaven forbid) and even this may get eyebrows raised by those who've spent my amplifier budget on their cable supports!
PS - I appreciate that well designed amps have internal barriers to prevent the power-carrying wires (unscreened) from contaminating the signal itselfSources - NAD M50.2 (streamer, CD player, CD ripper, hard drive music store)

Re: The Smith Chart and...Power Cords
I've found that with a sufficiently resolving system, pretty much everything (factor) makes an audible difference. For example, I can hear differences to due changes in barometric pressure or the difference between 68°F and 72°F in my room.
In addition to PCs, other significant factors that have audible effects are 1) room acoustics (this one is the most important of all) 2) ground-plane noise, both chassis ground-plane and signal-ground plane 3) leakage current, both as low-source and high-source impedance leakage current 4) threshold jitter 5) deterministic jitter and 6) phase noise. Digtal cables are susceptible to common-mode noise, and analog interconnects are susceptible to noise from the propogating longitudinal EM wave.
Speaker cables are particularly sensitive to vibration imparted to them from the floor (and no, it doesn't matter if the floor is slab or not; concrete actually "rings" like a bell).Ĥѱ = 𝐸ѱ

Re: The Smith Chart and...Power Cords
I bought a bunch of used Shunyata shielded power cables about 5 years ago. 3 x 1.5 M venoms and 2 x 1.5M Diamondbacks. Just to try out. Being an engineer by trade I trend toward the objective side.
I have an Audio Precision System 222 audio analyzer with the DSP option which can measure signals and noise well below the capabilities of commercial audio gear. So I did a little experiment. I measured the SNR of my MC 2301's with stock cables. Preamp was on, volume turned all the way down. SNR, A-weighted was: L -122dB, R -123dB ref full power. This beat Mcintosh spec by a bit, so was in the ballpark. I ran a 16,384 point fft and found 60 Hz components at L -131dB and R -131dB or about 8 dB below the broadband noise floor. Then I switched to the Diamondback cables. SNR, A-weighted, was L -122 dB and R -123 dB. Same as before. Then I ran the same FFT as before and found the 60 Hz components were L -140 dB and R - 141 dB.
So the Diamondback cables made a 9 dB improvement in 60 Hz noise of the output of my MC 2301 amplifiers. No, these cables didn't make a difference in measured A-weighted noise, but humans can hear tones 15 dB below the broadband noise floor. So, these cables made a measurable difference at the OUTPUT of my amplifiers. They moved the 60 Hz component below audibility. Did they sound any better? Yes, I think they did. They stayed in the system and I bought more of them. But of course that subjective statement is colored by the fact that I knew they performed better objectively.
Call it bullshit if you will, but there are real physical reasons why power cables may make a sonic difference. Power cables radiate strong magnetic and electric fields that decay at a rate proportional to the inverse square of the distance from the cable. Yes there are miles of transmission line between you and your equipment but no, those don't matter because they are miles from your equipment. Your power cords do matter because they are right next to your audio cabling. And yes, as a designer I can mitigate or eliminate their effects inside the equipment chassis itself. As an audiophile you can choose cables with superior electric and magnetic field performance, avoid running power and audio cables physically parallel to each other, and cross them at right angles with some distance between them wherever possible.Tom

Re: The Smith Chart and...Power Cords
a] were the Diamondbacks the same length as the stocks?

Re: The Smith Chart and...Power Cords
a) Yes
b) Yes
c) Yes, Mogami 2549 for the balanced interconnects. Speaker wire is Kimber 8TC which is multiple twisted pairs, unshielded.
I also measured the field strengths at the cable jackets using a Trifield TF2 EMF meter:
Stock OEM E Field 235 V/m H Field 42 mG
Diamondback E Field 3 V/m H Field 14 mG
At 60 Hz the predominate coupling mechanism will be H fieldTom

Re: The Smith Chart and...Power Cords
This discussion has been interesting. I know a fellow audiophile who has purchased a handful of Odin Gold Power cables. They list for $34,999 for 1.25 meters. Bet we know how he feels about the importance of power cables. In total, he has more money sunk in Nordost cables than I have in my entire system.
