  1. Spend your money on a better NUC PS. Or get a refurbished Cisco Catalyst switch with better behaved Ethernet ports to hang your NUC and streamer off of.. Ethernet cables aren't going to change/improve data packets already in flight but a better PS or Ethernet switch will make your equipment operate closer to ideal when handling origination and termination of data packets. Cables matter in the analog domain, if you feel the itch to experiment with better cables, Kimber Hero interconnects are a safe bet
  2. So explain why 2 data paths D- D+ can be called serial? Serial in my book means only 1 usable data path, all bits are sequential. if you have 2 or more data paths with clocking thats parallel data transmission.
  3. I went through this exercise a few months ago so that I could play music without it permeating other rooms. 1) use seam sealer (weather proofing) tape on the frame. 2) use an adhesive sweep of rubber like material on the bottom of the door Its a bit of a PITA to do the frame sealing because door frame tolerances are tight but its absolutely critical to get the air tight seal to minimize noise transmission. You can also buy door size hanging dampers for thin doors that don't block enough noise after sealing, kind of an audio lead apron equivalent
  4. USB and SPDIF are both wired solutions for sending digital data using analog (voltage) signaling. The difference is that USB is much faster because it has parallel signal leads where as SPDIF data is serial. It is more susceptible to clocking issue anomalies than SPDIF but can also be more precise when clocking is done right. It's hard to go wrong with the Zen Mk III for sound quality and USB out if you accompany it with a good DAC. The Phoenix reclocker is their Statement level product for maximum USB performance... for many of us while it would yield a result, that mon
  5. HDCD's have about 6db gain compared to normal CD. If the album hits peak limit more often, that may cause distortion for output. You may want to fiddle with recording gain to compensate since the apps aren't recognizing the disc as HDCD
  6. Nevermind... switched the NUC to WIFI and buffer speed is much better. Looks like my POE connection to router has problems
  7. FWIW I am seeing that HQPlayer current track is buffered to RAM with Stylus and Qobuz but it buffers slowly, like watching paint dry and the next track is never buffered by end of current track. Moving the port from FE to GigE on Etheregen speeds up Stylus w/o HQPlayer to reasonable buffering speed, HQplayer buffering speed improves modestly. Has me wondering if this is a network delay issue or do others get same slow buffering performance using Stylus/HQplayer/Qobuz?
  8. if you go this route, its important that your software defaults to a muted volume vs 100% after launch/reset.
  9. For both Euphony and HQPlayer you have to request that a new license key be sent if a detectable change occurs. You may want to swap the card in, capture the new signature(s) then put the old one back in for a few days until your request(s) with the new signature are completed. HQPlayer doesn't seem to detect a signature change until you try to play music using HQPlayer
  10. I think the question of RAM buffer vs disk cache is important... my suspicion is that Roon playback uses disk cache and that is why Stylus sounds better, because it uses RAM buffer. Euphony will no longer let you run Stylus or Roon server entirely in RAM, you get an error msg if you select "load app data" to RAM for RAM disk. Would prefer that option was still allowed for Roon, when I was using it the only defect was that any updates made after it was enabled weren't saved at shutdown, you had to occasionally exit RAM disk mode so that Roon updates and major library changes were sa
  11. I’m going to suggest you do your own check as that does not agree with observed behavior when I disconnect the ethernet cable during play. Stylus will always play the next song. When I use Roon with HQPlayer it stops after current song if Ethernet is disconnected. I’m also wondering now if Roon is buffering current song to RAM or caching to disk.
  12. So perhaps what we need instead of a speaker impedance chart is a wattage chart showing the power draw across the practical spectrum ( say 32hz to 16khhz) at a comfortable listening level 1 meter away, say 76 db and a loud level, say 90db? Although I wonder if there is linearity there... if you have 1 low bass tone, a mid range tone and a treble tone at same perceived level, do they measure at same db level?
  13. mehh... the audiophilleo was never cheap and its old for USB design. My Metrum Octave is a back up DAC now, first for a Schiit multibit Gungnir and then for a better sounding Chord mojo. If you like the more euphonic R2R sound a Lampizator Amber 3 might be a good investment, sounded quite musical when I heard it at CAF 2019. I used to always buy separate asynch USB devices but they have gotten good enough to where too much is lost when the USB section is external
  14. Its also a venue property. Some halls just don't work for knowing where the instruments are on stage.
