Best audiophile switch

Well, I did it. I ordered the SR Ethernet Switch UEF with upgraded power cord. I also ordered two SR Ethernet UEF Performance Enhancers. I'm not sending the loaner switch back until I get my new switch. Still experiencing chills and tears with this switch inserted into my system.

I just received today these UEF Performance Enhancers, ref attached photo. I get the chance to evaluate them right away with the loaner switch. Nice. They certainly stepped things up a notch. Bass immediately got even clearer and just overall sound is better. Best I can describe is I played some of Norah Jones' older songs and it now feels so intimate, like I am sitting at a table in a bar just in front of her and her band.

I can't get anything else done.

I use two enhancers too. One came with the bundled deal, along with a good ethernet cable and decent power cord. I'm using a Kubala-Sosna PC. The PC makes a difference, as one might expect.

In my setup, the performance enhancers took a few hours to get fully up to speed. While it all seems like voodoo to me, I believe there was a specific design goal to reduce noise without otherwise adding its own sound. Well, at least that is what I'm hearing. As you say, addictive!
 
Last week I built an isolation platform for this network switch. I made an 8"x12" platform with Qty (3) 11 lb/in compression springs. It didn't cost me much but time. I used some leftover wood from another project. This platform mechanically isolates the network switch from vibrations that come up from the floor. It is just as effective as my larger platforms that I made for my preamps and music server. I verified with an accelerometer. This switch is pretty hefty.

Conclusion: No change in the sound using an isolation platform. This means either the switch is not affected by vibrations or this SR Ethernet Switch is well built isolating vibrations on its own. It does have a carbon fiber top. This is the first component I have found not to be enhanced with isolation.

Still enjoying this switch on loan. Waiting for the new version release.

Also showing the isolation platform for my music server. I posted more detail about isolation in the vibration forums.

I dont believe that noise removal should change the character of the sound. If it is "warmer" or "harsher' these are terms of coloration or distortions.
WHen one removes noise there is just more of the music and more of the space with the music and between the musical players. This is one of those you dont know you what you didnt know until you know times
I thought noise could create a veiling of bass sounds. When the noise is gone, the bass can come through?

Interesting finding! Always helpful to assume nothing, try and listen.

Any thoughts about checking out the UEF Router?

No, I‘m not thinking that far ahead. This switch is still on loan to me while I wait for the new version from SR to be released. Once I get the new switch I will need time for it to settle in and I become accustomed to the sound.

My last major purchase was a year ago getting the new music server to compliment my new DAC that I bought 13 months ago. I have played records just a handful of times this past year so infatuated with the sound of digital and a universe of music compared to my paltry 1100 record albums. And then there is the efficiency advantage of digital over vinyl.

To play a streaming song the following steps must be taken:
Prestep 1. Unlock iPad using Face ID
Prestep 2. Open Roon app
1. Select song from saved albums or type in name in the search function.
2. Press play
Total time: About 6 seconds

To play a song on vinyl the following steps required are:
1. Grab flashlight
2. Peruse record albums on shelves using flashlight to be able to read album titles and find the desired album. 1-3 minutes. (Can be longer if album was not previously put back in alphabetical order.)
3. Remove album from sleeve. (In this case decision is not to use the record cleaning machine). 10 seconds
4. Use Zerostat gun, 3 pumps pointed at record center, then a fourth squeeze but hold until gun is pointed away from record to release trigger. (Specific ritual to remove static charge from record.). 20 seconds
5. Place record on turntable and install record clamp. 20 seconds.
6. Press power button on turntable and watch the Roadrunner speed readout stabilize. 30 seconds
7. Cue tonearm. 12 seconds.
8. Unmute the phono preamp. 3 seconds
9. Find your listening spot, relax to 26 minutes of beautiful music unless it is a 2 record set and then it is just 13 minutes of beautiful music. 12 seconds
10. When music is over, cue the tonearm remove flip record and repeat steps 4-9.
Total time to hear one album: 6 minutes prep time plus 26 minutes album time.

OK. Thanks. Since you are meticulous in your record keeping, might want to add a note in case of Roon or OS update ;)

For some, those 6 minutes are comforting and ensure that the planet is rotating properly. We digitati, of course, have our own rituals, which must never be revealed (nor the handshake).

Great that you have both.

I have one of those, cost me £20.

According to the graphic, the board is unmodified by Reiki. So it's a $25 switch in a $1400 box?
Copper is quite expensive these days. ;-)

honestly, if it took me 6 minutes to play a record i would sell all my records and turntables. OTOH everyone sees things differently. but that would effectively eliminate records for ME.

when playing records it does take me about 45 seconds prior to the first record of my session, compared to 5 seconds to play my first digital streaming track. so starting the session does take more time.
1--turn on both tt's--15 seconds. CS Port is one button behind for the air, hit the on button on top for the motor, spin the platter to get it going. for the Esoteric takes one button for on, then 5 seconds later after the clock is engaged, one button for speed. total for both 15 seconds.
2--turn on the EMIA phono, press each of two power supply on buttons, 5 seconds.
3--turn on both (CS Port IME1/DS Audio Ion) Anti-static devices---10 seconds.
4---turn on the Tana/Herzan active shelf under the phono (i leave the Tana under the Esoteric always on), then engage the decoupling---5 seconds.
5---turn on the DaVa cartridge field coil power supply, and the FCL field coil arm power supply----5 seconds.
6--turn on both tt lights---5 seconds.
7---if i'm playing pressings from my long term 8000 pressing record collection, i basically can lay my hands on any of them in less than 30 seconds. even in the dim/dark. they are all cleaned and ready.
8----if i'm playing records from my more recent 2000 pressing classical addition, which were all cleaned and ready last summer (it was my summer project), i grab 4 or 6 at a time from a section and play from a stack. it might take me a minute to decide where to grab a handful, but then i have a few to play through.

my vinyl sessions will last 90 minutes to 3-4 hours, and there is very little down time. having the records cleaned and having the CS Port and DS Audio anti-static devices really removes time between records, or to start, without much compromise in noise and when the records are put away they remain clean and relatively dust free.

we all have our processes, there is no good or bad one as long as you keep listening.

This is the insides of my LHY SW-8. I don‘t know about the cost of manufacturing electronics like this. It seems like it is much more than a $25 switch to me. Bottom line is this Ethernet Switch is effective in making the sound better and the the streaming picture noticeably better on my TV. I found this switch was an improvement over FMC‘s with Finisar SFP‘s and Linear Power supplies, which was an improvement over a direct ethernet connection or a cheap, $30 network switch.

I also find the SR Ethernet Switch to be a considerable step up in sound. I have it on loan so it is not that I am invested in it. However, I will be buying one. I‘m not touching the SR Switch as it is not mine.

some folks like stacking switches from different manufacturers. I haven't tried so have no opinion. Curious is you have tried the SW-8 prior to the SR UEF switch.

Of course. I have had the SW-8 for close to 2 years. I got the SR switch on loan a few weeks ago.

I also bought the EE-8 sometime back. Sounds about the same as the SW-8 to me. I stacked the two- the SW-8 and EE-8. The output of the EE-8 was dedicated to the music server while the SW-8 fed the EE-8, back channel wifi router and the Apple TV.

The SR switch is dedicated to the music server with a direct line to the router. Sounds extremely good.

Tony - Thanks for your observations. I have an EE-8 switch which provided an improvement, but not significant in my system. I kept it anyway. I am now considering the SR switch (and potentially router). But, it sounds like I should slow walk it as I now understand they’re coming out with the new switch soon. Complicating some things is that I have some potential interest in pursuing a Taiko Extreme or Olympus and might bundle in their peripherals. Just trying to sort some things out as I optimize things for my DAC.In any case, I appreciate actual user feedback more than professional reviews which always seem to be glowing.

You are welcome. And I used to think that the higher end gear would be more immune to variation in the ethernet stream but it seems the higher end gear responds more so to the quality of the upstream signal.

When I say the SR Ethernet Switch UEF sounds much better, I need to be more specific. It had two quantifiable improvements in the sound for me that I noticed the most. First, and the biggest improvement is in imaging. Imaging didn‘t just get more focused but it also got more stable. One thing that bugged me a bit before I had this SR Ethernet Switch in place is that the images would sometimes move around when streaming music. Voices might move to the right a foot or two and then moments later move back to their original position. I find that disruptive. Sometimes I would stop the music and replay that section and the image would be in the original position the second time and sometimes the image will still be moved over. (I don‘t mean the whole stereo image- just a single voice or instrument.) But since using the SR Ethernet Switch UEF it has not happened, not once.

The other improvement is in the bass. Every step of improvement on the digital side has been either in the bass or the highs. The bass now has detail and resolution like the midrange. And with better, cleaner highs I can play the music louder without that cotton in my ears feeling afterwards. Caveat- I listen at around 80dB with „loud“ for me being upwards of 88dB with some peaks in the low 90s.

My current digital side has PRaT rivaling my vinyl rig. To me now, my vinyl and digital sound are very closely alike. I think a system must either sound very very good or poorly mediocre for digital and analog to sound similar. There, I just made a very provocative statement. A statement that up to just a couple of years ago I would never have even believed could be possible.

And to that end I find the best of the best digital rivals the best of the best vinyl now on my system. But that doesn’t automatically mean all digital is better. It is now down to the mastering/recording for me. Some older music still sounds better on the original vinyl vs the digital remastering. And if I were privileged to have reel to reel masters it would probably be a different discussion altogether.

For me, the UEF switch lifted the SQ of 44/16 and also clarified further the differences in mastering/recording, especially for resolutions of 44/24 and above. It doesn't do this by highlighting. As I hear it, the differences are differences in style of recording (mics, etc.) and are equally valid. I can't adequately describe the differences, but can hear them easily and in most cases enjoy the various presentations.

The other switch benefits are greater depth and body. I assume that is due to the reduction in noise.
 
I apologize if this feels redundant after all the previous posts, but I’m aiming to summarize my expectations for 2025 in terms of using a best audiophile switch, while also critically evaluating my current audio network. Looking forward to what’s to come!

It’s not so much the network signal itself that matters. Rather, it is the environment in which the network signal travels, the signals it picks up along the ride, and how it interacts with the DAC/streamer that makes the difference.

An audiophile switch is not just for a NAS or an online streaming source and it affects both sources equally. In fact, a switch also influences the sound of music stored in the local library on the SSD of a server-streamer. Some can even hear the impact not only on all servers and streamers but also on components that may seem unrelated to digital audio, such as the preamp and power amp.

What this means is that an audiophile switch can influence overall sound quality and enhance the sound quality of music files on either side of the connection. (Remember to disconnect the unused switch from power when comparing A and B to determine the best one.).

If you don't hear the difference now, I hope you will in the future. Please keep this in mind when evaluating which switch to choose and its potential for improving sound quality.

Before investing in a new switch, take the time to assess your entire audio network setup. Identify potential weak points where noise or interference might occur. A thorough evaluation of your network can often reveal issues that, when resolved, may improve sound quality without the immediate need for new hardware. Isolating the audio signal, whether through a physical or software-based solution (such as a VPN), is essential for minimizing noise and achieving optimal sound quality. Pay extra attention to the last part of the network, including the final switch (since most use a first switch) and the last Ethernet cable. This last section plays a pivotal role, so investing in high-quality components here can have a significant impact.

If you plan to use a clocked switch (internal or external), it’s important to carefully evaluate its role in your setup. A higher-spec clock crystal, implemented with better associated power supply components, may have less interaction or lower emissions, contributing to improved sound quality. Additionally, clocked switches are highly sensitive to placement, and their performance can be influenced by environmental factors. Be aware that clocks require warm-up time to stabilize fully; it’s best to judge their impact on sound quality a few days after installation.

The power supply is another critical factor. Using the best possible power supply for your switch(es) (preferably also the first switch) can significantly reduce noise and improve overall performance. Many audio switch manufacturers incorporate advanced noise control and power supplies (and power management), which often justifies the higher price of these devices.

Two excellent points - neither of which are something one would believe unless they’ve dipped more than a toe into trying to address the harm their networks do to the music.

I didn’t quote the other points you made, but they were all just as worthy. Nicely done.

Thanks! What stands out here is how a good ’best’ audiophile switch doesn’t just improve the sound at the DAC—it elevates the entire network, even influencing areas we wouldn’t expect. By the way, remember to disconnect the unused switch from power when comparing switch A to B to determine which one performs best.

I wish it weren’t like this regarding the audio network—I’d much rather invest in my components than my network—but the reality is, it just doesn’t yield the same results!
