  1. look in the manual on the allo site. I was on there earlierlooking for an answer to my question. On the PCB there's at least one earthing point marked that i saw.
  2. I am powering the USBridge Sig with an Allo Shanti currently but I would like to introduce Ian's ConditionerPI which introduces an ultracapacitor filter into the GPIO power pins, see here: https://github.com/iancanada/DocumentDownload/tree/master/UltraCapacitorPowerSupply/ConditionerPi I already added a small ultra/super capacitor across the 5v input of the signature with a small improvement and my question is whether it's possible to power the USBridge signature from the GPIO or is power input only at the USB-C socket. thanks, Crom
  3. Hmmm, I can't say I've ever experienced that. In fact, I've just checked and I copied a couple of albums into a monitored folder before I put the kids to bed about 50-60 mins ago and they've appeared in Roon. Not sure how long but no longer than 1 hour...so potentially not immediately! I can't honestly remember what I used to create the network shares. I used NFS with linux but can't remember whether I got that to work on Windows...when I get a chance to check I'll let you know.
  4. Just in case this is useful for others with larger libraries...I've been using Roon for 4+ years now (my Roon DB was 60GB at last look and I've got over 240k tracks). Every few months it would crash the database and I'd have to restore some backup or other...a pain. I finally got around to raising a question on the board and a recommendation to run Roon Server on Windows came back. Since then I havent' looked back. The problem apparently revolves around Mono libraries that take care of .net duties on linux. Their just not as 'good' as the original libraries in Windows.
  5. I've just ordered a bunch of John Kenny's supercap psu's to try out. John's been a star over the years I've been into this hobby and I want to try out his latest product. My order consisted of: 1 x 19v to replace bog standard SMPS on an Intel NUC (running roon server) 1 x 12v to try out instead of MPAudio HPULN powering a supermicro motherboard which is running HQ Player, or perhaps powering etherregen. 2 x 5v to try out against various things: a) Some Paul Hynes regs that are currently powering 2 x bufallo IIIse-Pro boards, or b) a MPAudio HPULN powering JCAT netwo
  6. Not as NAA but I’ve been using this in one way or another for about a year now. Good little device. Plus points for me were: - 12v DC input - easy instant upgrade - ATX power input for even better power supply upgrade potential - PCI slot space inside the case (unlike the NUC cases) - ECC RAM (sounds better in my book but I'm not getting into that) - Xeon processor (again…sounds better in my book) - Supermicro board (usually super micro boards have easily accessible clocks to upgrade. Also I think super micro boards sound good…yes, I know) - SFP (not got around to
  7. Great stuff. thanks both. Last week I had Linux with a constantly problematic Roon database (NB - nothing at all to do with audiolinux, I really rate that distro. The issue was with mono libraries that are used under linux, by Roon). Documented issues here: https://community.roonlabs.com/t/roonappliance-system-private-corelib-system-outofmemoryexception/98175 Yesterday I had Windows 10 Pro. Last night I wrestled with installed 2019 GUI on a NUC (what a pain...network drivers, graphic drivers...). Anyway, 2019 is installed along with a shiny new upgrade to AO
  8. Hi all, I have been using AudioLinux for a few years with some good results but my Roon Database has grown to the point where I need to return to Windows, as RoonServer is significantly more stable on that OS. So, as a previous happy user of AO I'd like to explore its benefits once again but which operating system should I choose? I previously used 2012 R2 and from some initial reading I read that @AudioPhil recommended headless. I also read that @dminches commented that moving to server 2019 GUI would bring the SQ of previous server versions but with the benefit of a GUI. I also understa
  9. The immediate thing I noticed once I'd plugged it in (very heavy lifting alone!!!!) was that the bass improved. Fuller...there was just more of it but not in a bloated way. It was punchier too. Better bass transients in a system that I already rated as pretty responsive. Then there was better texture across the board. acoustic instruments just sounded more...acoustic. The cohesion comment came from how the instruments hung in space better. I place great importance in the soundstage on my system and this definitely improved it. Not really the scale of it, but the fact that it was all a little m
  10. ooh, exciting. I bought a second hand one of these last year - soundstange, bass, cohesion...all improved. A great upgrade in my book! http://www.one4power.co.uk/westwick.pdf
  11. I use JCAT Femto network card in my HQ Player PC. My audio chain is as follows: NUC Roon Rock server > HQ Player PC > ER > Endpoint/DAC Adding the JCat card produced a noticeable improvement a few months ago but the ER provided the more significant improvement.
  12. @Darryl R have you tried leaving the cat card in place and adding the ER between your bridge and dac? I’d be interested to hear results and if improving the Ethernet signal using the jCat made any difference/improvement at all.
  13. Yes, I'd appreciate that too. I saw the dietpi update available but skipped it for now. However, I've replaced dietpi with audiolinux and as I'm not using the USB out on the sig it's working a treat!
  14. What happened to this? Is this link just wrong or was it taken down? I was interested in trying the script out.
  15. In my mission to rid myself of constantly regenerating fingerprints from trying to use the combination of HQPlayer and audiolinux, I too would like to compare the difference in SQ with one of Jussi's images. Can I just check which one I should be downloading... From the jump in file sizes I'm assuming that the most recent builds probably have both the NAA and the HQPlayer packages installed...I seem to remember seeing that info in a post somewhere but can't find it now. So it seems like I should grab the 3561 image. However, I use a Raspberry pi 2B as my end point (beca
  16. I'm saddened ... but comforted ... to see that others are having the same problem as I. For whatever reason I have been completely unable to obtain a stable fingerprint on boot up (although it has now remained the same for a week!). My distro is audiolinux too. I wish Jussi and Piero would put their heads together and come up with a workable solution to this. Both are great bits of software and I have been using both in complete harmony for years...until recently. I understand that with software it is often very difficult to pinpoint the issue when there is more than one system in play, but us
  17. Take a look here: https://www.cisco.com/c/en/us/products/collateral/switches/catalyst-2960-series-switches/prod_qas0900aecd80322c37.html I bought an L version which was an improvement over directly feeding from a Ubiquiti switch. I then replaced the power supply with a quieter one which yielded another small step forward. Nothing huge, just a little more rounded, fractionally more 3d etc...worth doing though!
  18. ...and having spent hours fiddling around...then posting a shout for help, I manage to find a solution within minutes of posting. Gah, how foolish do I feel. I'd somehow managed to switch off the IPv6 checkbox in HQPlayer config page! Problem solved. Music returned. So...just for future reference, in HQ Player headless, does the interface get 'stuck' on the config page when there is a configuration problem? Thanks all and sorry for disturbing!
  19. Hi all, I've recently started to use the headless version of HQPlayer running on Audiolinux headless, running on a NUC. The NAA is running on a rasberry pi (also on audiolinux). I have been trying to troubleshoot a problem in that Roon is unable to see HQPlayer: This is a bit annoying as I had it working perfectly a few days ago and I'm not sure what I've done wrong! HQplayer logs indicate that it can see the NAA: 2019/05/04 12:03:25 asoundlib version: 1.1.8 2019/05/04 12:03:25 Found ALSA device: hw:CARD=PCH,DEV=0 - HDA Intel PCH: A
  20. Hi Poldi, Thought I'd chime in here as I bought one of the older models of 2960, see pic here: https://www.ebay.co.uk/itm/Cisco-2960-8TC-L-with-IOS-15-Catalyst-WS-C2960-8TC-L-2960-Managed-8-Port-Switch/113676988187?hash=item1a77ad2f1b:g:EZcAAOSwPEhcgRHF Not sure whether the new version is the same but I took the lid off mine and replaced the power supply (12v) to the motherboard. Then I earthed the motherboard. Both resulted in relatively minor audible improvements but i've kept them in the system. Of the two, upgrading the power supply was the more impressive. I might ge
  21. Hi Guys, I'm lurking with interest here - fascinating thread! Regarding the new process assignment feature in AL, a couple of years or more ago when I had a two PC Jplay setup running Windows, I used a program called Process Lasso to assign certain processes to one or more processors. Whilst the impact was not enormous, there was a noticeable improvement and that was on top of motherboards that had clocks replaced, battery-run Compact Flash cards as hard drives etc etc. I've done a v quick scan and the software is mentioned in this thread: http://jplay.eu/forum/index.ph
  22. @jabbr how did your mezzanine power hat go? I've just ordered afully populated board and a bare one for additional hacking!
  23. Yep, good point...but it would be great to find a platform that could run HQP effectively and be powered by a quiet power supply. Clearly that graphics card is going to need a beast of an ATX psu. I previously ran a xeon-based supermicro board with a set of DIY linear power supplies. It didn't have the horsepower needed for HQP so I've replaced it with a more powerful desktop system as an interim solution. Comparing the two platorms using HQP with v limited upsampling demonstrated that the better power supply was the way to go but that the more intensive algorithms and higher upsampling able t
  24. Now the Xavier does look interesting: https://www.nvidia.com/en-gb/autonomous-machines/embedded-systems-dev-kits-modules/ Could it be the answer to upsampling to 512 DSD with HQP (using one of Miska's more intensive algorithms) without having to live with an Intel monster CPU, fans etc?
  25. Thanks for taking the time writing this up - very interesting!
