  1. Thank you @plissken for starting this thread. It has been extremely useful to me. But not to learn anything new about the EhterREGEN. I have it in my system, and that's the best way to judge a component. The reason I find this thread so useful is completely different - it is like a gold mine with extremely valuable info! But only to help me update my "ignore list", a new forum function I just learned about :).
  2. That makes sense and is inline with what I was thinking. The fiber-isolated USB module and the ultra low noise clock in the MSB DAC must be reducing the influence of the upstream components quite significantly, but like with other products, they are still there. Otherwise a different USB cable or upstream server would not make a difference. I am sure that even a MacBook would sound really good, but if you want those last bits of performance and refinement, the Taiko Extreme would do it. BTW, it's the same with my EtherREGEN switch - while it almost annulates upstream effects, the word "almost" plays a key role here. Thank you for the feedback.
  3. I am a little bit confused what are you trying to say here. I was trying to say that many manufacturers make claims that upstream devices don't make a difference, but I have never heard a DAC yet that is completely immune to upstream devices (never heard any MSB DACs, or the DCS DAC Rajiv reviewed, in my system, though). I have heard the opposite many times - changing upstream devices makes a bigger difference that changing DACs. By improved upstream clocks I did not mean daisy chaining a bunch of USB de-crapifiers between the server and the DAC. I am pretty sure if you try to do that with your Taiko Extreme, you would end up with worse quality after all. But your Taiko, according to Emile, has something that works better than OCXO clocks, whatever that is... There are obviously clocks in every computer. What I actually meant was generating a clean, low-jitter, low-noise digital signal that goes directly to your DAC. That's what Taiko Extreme (and any other good quality source IMO) does. So, are you saying that devices upstream from the MSB Select II DAC with Femto 33 clock don't make a difference? If that's the case, hats off to the MSB engineers. But does that mean you can replace your Taiko Extreme with a MacBook (or a NUC, or another genetic computer) and you won't hear any audible difference? I thought you were saying that the Taiko Extreme does make a big difference. So I am a little confused exactly what are you trying to say?
  4. That's a different transceiver. Here is the one Emile recommended - https://www.amazon.com/StarTech-com-1000BASE-ZX-SFP-Transceiver-Module/dp/B0747WZ8LZ/
  5. I just tried the SR orange fuses on my DAC and computer power supply, and I quite liked them. Thought I would share.
  6. I have about 10 of these cables, professionally built with: - 16 AWG Neotech 7N solid copper wire - JSSG360 shielding - WBT silver solder Some of them are with 2.1mm DC barrel plug, others with DC 2.5mm plug. GX16-2 plug on the other side. But I can easily change the plugs on either side to fit your requirement. These are well broken-in with thousands of hours. I have replaced all of them with new cables using the Mundorf Silver/Gold 15.5AWG wire... and just realized how many of these I had laying around. $65 per cable for one. $60 per cable for two or three. $50 per cabled for four+. Shipping in the US included.
  7. Upgraded mine. Super easy. Great instructions. Thanks, Alex.
  8. I know it's an 8-pin connector but not sure which type. Can someone post a picture of the connector?
  9. This is cool. I have been playing with my EtherREGEN, and although my feedback about the switch is positive, I have noticed that nothing beats the quality of 100% buffer and minimal/no I/O activity. The best sound from my source is achieved when there is no extra I/O activity. I would love to try that new UI option.
  10. Do we really need to argue about that? Hyper-threading is an Intel proprietary technology and not available on my AMD Ryzen. I did say that I tried SMT on/off. Let's move on...
  11. Cool. What are you planning to do to fix this? You may benefit from optical isolation - fiber media convertors like the Sonore OpticalModule or even some cheaper ones work great. There are some medical grade Ethernet filters like the Baaske MI 1005 that can potentially help. There is the gigafoil v4 isolator too. A JCAT NET Femto card also works great with or without some of the other methods. Network cables where the shielding is not connected to both ends typically work better in those situations. There are many ways to fix that... I have settled on an EtherREGEN switch with a JCAT NET Femto NIC and an AudioQuest Vodka ethernet cable for now.
  12. I use AMD Ryzen, so there is no such thing as hyperthreading. But I did play with SMT on/off and various CPU isolation settings and have settled on the settings that work best in my system.
  13. Start playing your local files and unplug your network cable. Wait a little bit... do you hear a difference? If you do, you have heard the positive effect of removing the noise entering your computer through your network port.
  14. I look at my digital source as one system from the file you play all the way to the analog output of the DAC. Everything in between is a complex chain - software, hardware, power supplies, cables, clocking, DAC interface etc. etc. - they all interact with each other. It is especially important how the computer interacts with the DAC, what conversion stages the source is going through, and how they affect the overall sound. Everything needs to be optimized for your particular system. Hence, I don't believe there are many universal BIOS settings that you can apply to every system. - First, there are unused things you can turn off from the BIOS like the audio card, any unused USB ports, other I/O interfaces, etc. Basically the less chips are working, the less EMI your motherboard would generate, which typically results in less jitter / better overall sound quality. - Second, you have some power settings. Some people tweak their system for using less power. I guess the power supply is one of the big factors here. - Third, you have performance settings - turbo, hyperthreading, CPU speed, RAM speed, etc. Those settings overlap with the power settings, because you can reduce the performance to reduce the power usage. They also depend on the quality of the power supply, the hardware, OS, the player and so on. I started with a system tweaked for lower power consumption / lower performance. As part of that I was disabling turbo, reducing the clock speed, and doing some of the other things mentioned above. But now I have a system that is tweaked for performance - power draw is not an issue - I have 16 cores doing almost nothing and tweaked for low latency / high performance. And that system, which is also much more expensive, sounds a lot better. OP probably wanted a universal list of BIOS settings, but I don't think it is that simple. Knowing what you are trying to achieve would help narrow down some of the choices and things to try.
