Only factor was the fibre switches themselves had a sonic signature.A few years ago, I wrote How to stream TIDAL to the Raspberry Pi. I’m on the yes it does side of the line.įor a while I used battery powered fibre switch for the last run to my Devialet Dual Mono Expert system. There has been untold discussions longer than a Russian novel as to if Ethernet connection have any impact on SQ. The clock in your system closest to the DAC will most impact your sound and the quality of it. The Lumin would have been designed ground up to have a result and in this case that out performs your PC. I would hazard a guess and offer up my humble opinion that aside of general external electrical interference, back emf from your gear, vibration, both mechanical and electrical, and the overall synergy of your system as a whole that the clocks in your win server are impacting the sound quality. One thing that I feel is regularly overlooked when I comes to this area of discussion is the impact clocks have. Lots of interesting and valid comments above. I wonder if I get a dedicated streamer like Lumin U1 Mini or the Bluesound Node 2i and use its streamer to feed the Teac DAC, SQ could be enhanced or even degraded. It could be that my systems are hyper sensitive. Even with a cable change alters the sound. My guess is that the SQ from different piece of software can never be 100% identical. The sound from Roon is closer to live music, only if it could be a bit more transparent then perfect! BUT on some recordings, Lumin sounds more edgy/ bright at loud passage. warmer than from Lumin app, but still not as transparent as Lumin’s. Roon SQ seems more dynamic, holographic 3D. swap RCA cable from Purist Audio to Harmonic Tech Teac to CJ preamp- with this change the sound also change from warm to a bit bright.Plug the Asus router to the same power conditioner as rest of system. installed a switch in my HT room, connecting existing 50ft Cat 5E cable from the cable modem/router upstaiirs, then extended it with Cat7 or Cat5E (i tried both no SQ difference) 35 feet to the ASUS router which sit next to the Teac streamer/DAC, then use a 3ft Cat 5E cable to the Teac.I have done few things last couple of days: I have read several articles recommending connecting the server and renderer to the same switch to shorten the signal path. So perhaps the best answer is to have the music source closer to the renderer. ![]() I notice no material difference between Roon and LUMIN app. I also have an upgraded power supply on the audio system switch. Short cat 8 cables used on both, with a 30’ run of CT 5e to the switch serving the audio system. I have a LUMIN U1 mini connected via Ethernet to the same Ethernet switch to which my MacMini i7 music server is connected. Perhaps the LUMIN app is better at handling weaker or noisier signals than the Roon app. Maybe there are code differences in the different softwares. ![]() ![]() Same signal path so in theory there should be no difference. Minimserver and the LUMIN app, I agree with you. It’s why Roon recommends using a local USB drive connected to their Nucleus vs. ![]() The USB drive direct to your TEAC sounds better because the signal path is extremely short.
