  1. Great review, Rajiv. Actually reading this at the Odd Duck on S. Lamar. I dig your city! I will admit that the thought of a DAC that can't be improved with upstream tweaks scares me a bit... I guess I'd have to learn how to build speakers!
  2. Hi @austinpop, thanks for the update! Did I miss something? I hadn't realized you went back to the Roon server + SoTM solution from the Euphony + Stylus one-box solution. Any update here? Or have I just gotten lost in the morass that is this and the other threads?
  3. I find the type of DAC used determines whether upsampling is beneficial as well. For instance, my Chord 2qute sounds much better with native PCM than upsampled PCM or DSD.
  4. Actually many folks here rely far more on their ears than measurements. You'll notice no measurements have been provided supporting many of the claims made on this forum. What counts is whether or not, once you test a claim, you agree or disagree with the OP (e.g., @romaz, @austinpop, or @lmitche). That being said, I've definitely purchased what I thought was an amazing piece of equipment only to realize music quality decreased once I added it to the chain.
  5. How do you deal with enclosures and making holes for the IEC connectors and barrel plug / XLR outputs on the PS??
  6. Ramroot is really the value-add step IMO. It is very easy to set up - I have complete confidence you'll get it up and running in no time, especially since you've gotten this far! Good luck.
  7. Thanks for the review! Does Adrian have detailed specs on the power supply? Is the regulation discrete or does he use LDOs?
  8. A random and very innocent follow up question... Would the same be true with a JS-2?
  9. The more I listen, the more I think Audiolinux booted from RAM is just a whole new league from what I've experienced with the Allo Digi One bridged... and I'm still using a SMPS for the Brix running Audiolinux (and so is my DAC... and the ISO Regen feeding it as well)... I have a long way to go, but RAM booting headless Audiolinux is equivalent in my eyes to the impact of network bridging.
  10. Apologies on this question - I just loaded the filesystem into ram, and there's another big improvement. So AudiolinuxEXTREME loading into RAM via ramroot command. Any other line-command tweaks?
  11. Hi Everyone - Are there any other line-command tweaks I should be applying to fully optimize Audiolinux headless? Or is stock "extreme" mode good enough? I got AudioLinux headless up and running after using the GUI version for the last few weeks. As I don't have a LPSU powering my Brix (yet). There is definitely an improvement over the GUI version. I'm booting into "extreme" mode. Thanks!
  12. Roy and Larry's findings seem to imply: 1. More cores are better 2. Linear power supplies are better (and PH Dual Regulation is the best) So, I'd venture to guess the answer to your question is... it depends on the processor! So, from what I've read so far, I'd rather have a low power i3 or i5 NUC passively cooled powered by one linear power supply than shelling out the extra $ for a low power mini-itx board that requires 2 power supplies. At least on the renderer side. It's too bad that we can't just get a great one-box server / renderer solution. That truly is the holy grail. It, though, is impossible to fault Roy, Larry, and the rest of the pioneers on this thread. How many thousands of dollars and hours have they spent for our benefit? I'm still trying to DIY a decent linear power supply (working on a sigma 11 over here)!
  13. Uptone JS-2? Let us know if the schotkey diodes, r-core transformer, and traditional regulation outdoes the Sigma 11!!! I say this as I am mid-build into a sigma 11.
  14. Hi Mark - I'm mostly a lurker that implements cost-effective versions of suggestions presented on this forum to improve my system. I have indeed noticed substantial improvements as a result of some of the changes suggested here. My two cents with respect to your situation are as follows: Figuring out "why" making a change causes an improvement is great, but not necessary... I, for one, want the sound improvement more than I want to know why I got that improvement in the first place... An important assumption here is that you have to be able to trust your ears so you can assess the size of the improvement... we can't measure everything... all we can do is try what others suggest and see if it makes things better or worse Sometimes a change highlights other deficiencies. I recently bridged my PC to my Allo Digi One, changed the connection speed to 100MBPS half duplex, and JSSG360 my BNC cable feeding my Chord 2qute from the Allo Digi One. The result was thrilling - a lot more definition and heft across all frequencies, a darker background, and improved dynamics. However, the sound became much "harsher" in the high frequencies. I have no clue why, but I suspect the Chord's switch mode power supply, the Allo's iFi iPower, and the source computer's switching mode power supply are contributing to this. I could try grounding all the switch mode supplies, but I'd rather just install some decent LPSUs. Since I'm poor, I plan on building a few Sigma 11 PSUs from AMB instead of purchasing more expensive units. I also plan on implementing an AudioLinux based server solution after that (see posts from Roy and Larry). One improvement begets another area for improvement. The work never ends. And I'm grateful for that. Don't give up easily! The struggle is the fun part - it is where we learn the most. I would fiddle with different connection speeds for the bridge. I would also ensure you have the latest LAN drivers for your NICs installed. Sometimes doing basic blocking and tackling can solve problems. I wish you success in your bridging quest! Nikhil
