I did get my system setup. I have also dabbled with variations of equipment, and software.
My network involves a UniFi router, and 16 port main switch. Excellent WiFi in the house, and a new copper Ethernet run to a jack behind the stereo. I have Premier DAC with Digital Director loaded with Renderer V2, the basic USB (sometimes connected to desktop), and optical SPDIF (video input) 99.99% music listening via Renderer V2
Equipment trials
Roon core on NUC Rock (music database on NUC, QNAP, and UniFi NAS)
Ethernet straight from main switch, and with a switch at the stereo system rack (all video components getting WiFi connection)
Software trials
Roon (ran on QNAP and NUC)
JPlay (via MinimServer on QNAP)
Audirvana (running from QNAP and PC)
Qobuz Connect
I have a modest system (ModWright tubed pre-amp, Atma-Sphere Class D monoblocks, and Daedalus Audio Muse Studio speakers). I also have 67 year old ears with a Texas history of rifle and shotgun use (I was, finally, using hearing protection during my sporting clay years), and a 40 year history of power hand tool use as an orthopedic surgeon.
I could tell little to no difference in sound quality in all the above experiments. My theory is that the combination of Digital Director and Renderer V2 levels the playing field. As noted above, usability, and user experience, is what wins the day. I am finally seeing that with some Roon competition shows up now and then, and seems to be gaining. I’m seeing more and more integration of AI into the mix. AI is the only thing, to me, that will be the magic bullet to getting appropriate new music suggestions.
I don’t have, and don’t plan to have, any sort of high end streamer box, using the different USB, or SPDIF/AES, connections. I don’t doubt they are wonderful, but not for me.
My next trials
Loading Linux onto my NUC, and hosting Roon core, and MinimServer. Music files are already located on the UniFi NAS. If I can get this up and running, the QNAP will be relegated to backing up the UNAS. Lots of learning, and experimentation, to go. Building DIY Aleph J amps currently though, so music server work on the back burner.
