Hi,
got a question for the appropriate use case for the Omega Ethernet: Is my understanding correct that it gets plugged between the LAN Router and a streamer? ... and if so: Do you guys use any special high-end router or the standard $50-100 boxes? I was just wondering: Okay highend Streamer with high end Ethernet cable and than cheapish router?! Is that the standard set-up?!
If what you're referring to is an Ethernet switch* (as opposed to a router), get an EtherREGEN (ER) Ethernet switch, and at the "downstream end" (where your rack and streamer is) connect your router and music server to EtherREGEN with Ethernet cables on the A-side. Then connect your Omega Ethernet from ER's B-side to your streamer. EtherREGEN only costs USD $640 and ships world-wide:
EtherREGEN – UpTone Audio
If like mine, your router has some RJ45 ports on it for making network connections, you will still obtain considerable benefit by installing an UpTone Audio EtherREGEN between your router and your streamer. You can use any generic Ethernet cable to connect from your router (or switch) to the A-side of EtherREGEN but...it does sound better with a Shunyata Ethernet cable (even Venom is an outstanding performer for this application).
Fig. 1 shows a conventional setup using copper Ethernet making a direct connection from a router with RJ45 ports.
If you require an Ethernet switch from your cable modem or router to make all the necessary "upstream connections" (modem, router, music server, NAS, etc.), you can use a generic Ethernet switch
upstream and then use EtherREGEN
downstream as shown here in Fig. 2. Just using a generic consumer-grade Ethernet switch (or even the $1000 "audiophile" SOTM sNH-10G Ethernet switch) WILL NOT sound as good as it wiil when used
in conjunction with an EtherREGEN downstream; rather it will cause all sorts of problems that are audible (see below for explanation of this).
If it's more convenient, you can use optical fiber to connect from the upstream router to ER downstreams. If you do this, I recommend the Sonore OpticalModule as your fiber media convertor. This will have the same clock that is in ER as it was designed by the same Ethernet engineer, John Swenson.
Fig. 3 shows using a fiber media convertor (Sonore OpticalModule) to the (usually longish) run from the router, switch and music server down to ER in the rack.
The ideal placement is to have ER as your last network device downstream in, or near your audio rack where the streamer is, with nothing between it and your streamer.
Using the EtherREGEN as shown above will result in a significant improvement in the audio quality of your streaming system because the el cheapo clocks, flip-flops and PHYs in "generic" routers, Ethernet switches, and mass-market music servers (e.g. a laptop or Mac Mini) add clock phase noise, and the switch mode power supplies for these add low- and high-source impedance leakage current, which contributes to considerable noise on the ground plane of the analog voltages that comprise "digital bitstreams". The clock phase noise and leakage current contribute increased jitter (as well as specific class of jitter known as
threshold jitter) and timing errors, all of which are audible. ER has a differential isolation system known as the ADIM, that will completely block all the "junk" from the upstream networked devices (and their god-awful SMPS power supplies) from going out to your streamer. ER's ADIM (aka "the moat) remove all the leakage current and other garbage upstream and ER has a very good crystal oscillator, the Crystek CCHD-575, that will remove the phase noise and reclock the signal. All this will improve the audio quality of your streaming setup
considerably.
If you want to know more about this in detail, I will provide some references, but trust me, it gets
really deep, really fast.
There is an extensive review of ER here:
UpTone Audio EtherREGEN Review and Comparison - Reviews - Audiophile Style
There is an outstanding review of ER on YouTube by Hans Beekhuizen here:
UpTone Audio EtherREGEN audiophile switch - YouTube. Hans review is very accurate as far as my personal experience with ER for almost a year now.
My review of EtherREGEN will publish in
TAS in the December "Digital Devices" issue.
UpTone Audio ships direct worldwide and has a 30-day no-questions-asked return policy, so you can order it in, and if you don't think it provides an audible benefit that is a value at it's price, you can return it, no questions asked, for a full refund. But, I seriously doubt you will return it. As of two months ago, UpTone had sold over 1500 ERs, and only...5 had been returned. That is a return rate of 0.3%.
*– the actual router that most people use is generally provided by their ISP, and most folks don't switch this out. Instead, they install an Ethernet switch between the router if they need to connect multiple network devices.
