  1. On my NUC with Gentoo Player there is no setting in my UEFI BIOS to control the functionality of the physical power button. This means my only way of doing a controlled shutdown is from Gentoo’s web interface (other than hard shut down). Is there anyway to code Gentoo so that a single press of the physical power button on the NUC will trigger the shutdown sequence? Not a problem for Raspberry Pi as they use so little can just leave it running, but a NUC I would rather switch off when not in use. Would be convenient if the web interface didn’t need to be accessed. Thanks & great work with the SACD feature.
  2. Wow - sign me up. Looking forward to further posts.
  3. @Energy Great post, you've earned your title of Audio Sophomaniac 🙂 Wished I'd crossed paths with you earlier when I was doing my VRM & power supply experiments. Due to my lack of success I'd then given up on the idea of being able to design something which betters the NUC/SR7 combo. The information you've shared makes me think your ideas are very promising! As you say, power supply is key - I am happy building using off the shelf modules and can also stuff and solder through hole PCB's, but no way I could design from scratch. Are you able to flesh out your proposed build / products /designs being used for the power?
  4. Sound technical reasoning... I did some experiments myself on motherboard VRMs and power supplies. What I found was that my 6 Phase ITX motherboard (msi z97i) sounded better than a 24 Phase Gigabye one (it used doublers mind). Sound was perhaps more detailed on the 24 Phase one, but it lacked transient attack and timing qualities of the smaller ITX motherboard. I now think low impedance is probably more important than ripple now. Some feedback I recieved. I looked at Belleson regulators, but never progressed - very interested in feedback on these as written reviews are not really available (?). How are you configuring them - in a linear supply? I tried Corsair ax1600i (lowest ripple ATX SMPS available, uses GaN Transistors), but NUC + Paul Hynes SR7 still sounded better (more dynamic) to me.
  5. Not entirely cheap then...
  6. Did you manage to find a price for the DFI GH171?
  7. I made no adjustments from the standard install other than enabling RAM boot - sounds great to me without further tweaks. I have only compared upnp on Gentoo Player vs Euphony, and found Gentoo Player superior (and free). You should notice an uptick in sound quality, but a laptop will be a noisy source (the screen built into laptops is apparently a large source of noise). Pick up a cheap NUC like I have, or a Rasberry Pi and run it headless for best effect. My limited experience is that the more powerful processors in NUC's give a more dynamic sound if that is to your liking (your mileage may vary).
  8. Any ambitions to configure gentooplayer as a bonjour service, so for example gentooplayer.local can be used to access the wbesite interface rather than IP? Is there an option in the web interface that will tell Gentoo Player to permanently launch to Ram Disk upon boot?
  9. Issue resolved - Gentoo Player on my NUC was not the issue, it was my the laptop upon which I was trying to access the web interface - rebooted this and no problems now.
  10. Hi - using web interface I now get the following error when executing any script Calling the script... Internal Server Error I have restarted the NUC and checked network connect - any ideas? Playback still works fine.
  11. Anyone else powered their DSL router using a linear power supply? I am also wondering what effect it might have if it's so far downstream...
  12. Feedback regarding Tidal via uPNP to: HQPlayer Embedded (32/768kHz, Sinc-M Million tap filter and 'LNS15') compared to MPD/UpMpdCli (no upsampling) Linn Kazoo as the control software, Hugo 2 as the output DAC. Hugo attached directly to the NUC via USB cable. Ncore monoblocks and Kef R3 speakers. ...both sound much the same to me. Perhaps slightly more detail and space to HQPlayer, but lower noise floor to MPD/UpMpdCli. Not much in it really. Both sound great, but if I was to choose I would probably go with MPD/UpMpdCli because of the percieved lower noise floor. Noise floor would probably be better if I ran HQPlayer on a separate machine, so that would offer some explanation. Also, Hugo 2 is a very good DAC anyway, so perhaps less benefit from upscaling / audiability in my system. An enjoyable experiment.
  13. Excellent add it to the Web interface 🙂
  14. Playback via Networkaudiod using Gentoo player as a renderer only works great - but running HQPlayer Server on my MacBook Pro meant I could only undertake basic upsampling... I therefore swapped to using 'HQPlayer embeded' as available within Gentoo Player installed on my NUC (as it's got a much faster CPU). Enabled Bubble uPNP (accessed via, as opposed to Port 8088 for Gentoo Player config on my system) and you can set HQPlayer up as an Open Home Renderer. I can therefore play everything using Linn Kazoo (other apps available), including passing Tidal (or Qubuz) through for upsampling via HQ player. I am using Sinc-M (Million tap) filter and 'LNS15' noise shaper as these are apparently a good proxy for what the Chord M-Scaler does. There is a fair wait/buffer between files (and my NUC runs hot!), but absolutely no stutter during playback - sounds great and will spend some time comparing against upnp direct (no upsampling) via MPD/UpMpdCli at some point. Really amazing work - I can't tell you how much better my experience is with GentooPlayer compared to using Audiolinux (high level of understanding still needed though).
