  1. I am planning to try their i2S cable and compare with a decent HDMI cable and a DIY cable from a really-really good 24AWG 5N solid silver I have been using for years. I am also planning to compare two AMD-based motherboards - an Asus gaming motherboard (ASUS ROG Strix X470-I) with a AsROCK server motherboard (X470D4U) with ECC RAM. Keep you posted on that as well.
  2. Based on my OS tweaking experience so far, I highly doubt it. But we would not know for sure until we get one.
  3. Thank you, John. Will patiently wait and try when the time comes. +1. That's exactly what I was thinking too. I have witnessed similar sound quality degradation simply from scanning my local library, even with the network cable unplugged. So I agree that it's more likely the result of the interrupt processing. Let's move on. We'll post the outcome of our tests in another thread when we have an EtherREGEN in our hands.
  4. It was an exaggerated example, mainly for illustration purposes to the responses saying that 100Mbps is more than enough. Yes, I am using Euphony at the moment, and the example I gave is not exactly how Euphony works. This is getting a little offtopic, so if @Superdad decides to delete, please go ahead. The gapless playback algorithm in Euphony definitely helps with slower bandwidth. But I have also noticed that those Euphony background processes decrease the sound quality in my system, even with the powerful i9-9900K CPU. They consume very little of the CPU, but it is still an audible decrease in sound. In some cases when I see more than a couple of cores using over 1% CPU, I would restart the Euphony app (which kills most background processes) and all of a sudden the magic comes back a few seconds later. And the sound becomes much better. I have done this a number of times and the effect is always the same. So while the gapless playback algorithm does what the name says - it works in the background to cache all tracks from the playlist to my Euphony cache drive (i.e. a partition on my Optane card), it also decreases the sound quality. Obviously the longer it runs, the worse the effects are... or I should say the longer the negative impact of this background process is sustained for. In my example of 10 large DSD tracks, once you click play, you would wait 80+ seconds for the first track to start playing, and then in the next 12-15 minutes a background process would be downloading the rest of the album to my Optane card. So somewhere around the end of track #2 or #3 the sound quality would become optimal. Or at least that's what I would experience in my system. I would like to reduce that negative impact 10 times by using 1 Gbps instead of 100 Mbps. But here is a more simple example - Let's say I want to browse my library and jump from one album to another. That would be a painful experience with "Buffer before playing = 100%" enabled for the tracks that are not yet cached. I may have to wait 80+ seconds for every track I click on. Or maybe not 80+ but you get the point. I have used an industrial grade 100 Mbps fiber media convertor which sounded great (especially after I upgraded its power supply caps and fed by a good LPS), and have experienced that with Euphony. If I added a bunch of new albums to my library and wanted to quickly scan through them, I had to either bypass the 100 Mbps media convertor or disable the "Buffer before playing = 100%" option. In some cases I ended up switching from Stylus to Roon. Roon has no issues with 100 Mbps bandwidth but it just does not as good. Hopefully that adds a little more clarity as to why I asked my original question. I can think of a few different ways of doing that but wanted to hear from the experts who designed the EtherREGEN if they have a prefered solution for that scenario. It's clear that crossing the moat gives best results and that the best thing to do is not to connect anything on the side where the server resides. But given the @JohnSwenson designed both, the EtherREGEN and the opticalModule, he might have some inside knowledge of what might work best. Regardless of the outcome, I am still getting an EtherREGEN as soon as I could get my hands on one /we are really hoping for this October(EtherREGEN)Fest :)/. . And trying in my system would be the best way to find out what works best for me. If that's the answer, I accept it, but it does not hurt asking, right?
  5. I guess I need to explain how pre-loading in RAM is different than streaming. Not all the DSD files are that big, but some are. Let's take an extreme case. It takes over 80 seconds to transfer a 1GB file over 100 Mbps connection. So let's say hypothetically that I have an album with 10 DSD tracks of that size. Here is what happens: - I click play. - I wait 80+ seconds for the file to load in RAM. - The track start playing. The music stops at the end of the track. - The second track starts loading. - I wait 80+ seconds for the second track to load. - Repeat the same process above for the rest of the tracks... 1 GB file is a very extreme case. Most of my files are much smaller. Let's say an average file is 150 MB. That is still a 12+ seconds gap between tracks. That would be quite an unpleasant experience over 100 Mbps connection. If we bump it up to 1 Gbps connection the gap would be just a little over a second on an average file size.
  6. And I would have to wait a minute after every track until the next one loads in RAM over the 100 Mbps connection. If it was not clear from my post - I am trying to avoid the traffic from the NAS to my server to go over 100 Mbps connection.
  7. One server solution. Local files are stored on a NAS. The server loads the entire track in RAM before playing. Apparently to get the most out of the EtherREGEN, we need the signal to cross the moat. That unfortunately limits one side to 100 Mbps. Some larger DSD files would take quite a long time to load in RAM over a 100 Mbps connection. I am thinking what would be the best way to implement the EtherREGEN in such case? So far, this is the best idea I have come up with: Streaming Tidal / Qobuz would go across the moat, that would be quite beneficial. Loading tracks from the NAS to the RAM on the music server would have to be done over 1Gbps connection. No crossing the moat, so not using the most benefits of the switch. But adding an opticalModule would help isolating the noise from the NAS and would also do some reclocking (not as good as EtherREGEN if I understand correctly, but at least better than nothing). The JCAT NIC also has a good clock, so perhaps that would be an acceptable compromise for this use case. @Superdad @JohnSwenson - do you have any better suggestions? Thank you.
  8. @austinpop Have you considered sending that ASRock motherboard to SOTM to replace the clocks?
  9. Look at Sean Jacobs too - he can make you a custom LPS, and they are really good, but expensive - http://www.custom-hifi-cables.co.uk/home/power-supplies/dc3-power-supply
  10. I would not use water cooling in my system. I don't like the 'wet' sound! Just kidding. Any type of vibration is an enemy and reduces the performance of your clock. That's the main reason I do passive cooling, not because of the noise of the fan, which is much quieter than my A/C. Water cooling is not vibration free.

    Same OS, different kernel versions, and different tweak options. In terms of tweaking, here is how I see it: In terms of sound quality, if you get the right combination between all the knobs on AL, one might be able to make it sound like Euphony. If even one of the knobs is a little off, it would sound different. Better or worse would depend on the settings, your system, room, and taste. I purchased both but use Euphony.
  12. Everybody likes charts and numbers. Hopefully you realize what you are asking is impossible. There are so many variables in a system. Sometimes it's difficult to definitely say between two components which one is better. Sometimes it is easy to say. For example, my $300 Allo DigiOne Signature does not sound nearly as good as my current computer where I have probably invested $5K+ in parts. And it would probably be a no brainer comparison in any room / any system. But there are many devices that just sound different. If they sound different, it would be a subjective opinion in the system and in the room of the reviewer. Perhaps in another system and another room, the reviewer might pick the other component. And that's with just two components. You are asking about top 20 rankings. You will never get an answer to that question. There are almost 600 pages of super valuable information here. And there is no consensus on most things. Perhaps the only thing people agree about is that the power supply on the device connected to your DAC makes a difference. But then there are people who argue that the power supply on the streaming server does not make a difference. Read and get educated from other people's experience. Try some of the things and see what direction you want to take. As for the best servers, look up Taiko Extreme. That to me looks like the top server on the market. But I've never seen or heard one. Check out PinkFaun 2.16x, Innuos Statement, etc. There are plenty of options at any price level.
