My Roon setup is largely the same as I described here 4 years ago. I still use a Core i7 Gigabyte BRiX running ROCK. When I wrote then it used to be on Windows 10, and and I have to say I LOVE, LOVE, LOVE the ROCK as it has been totally seamless, not getting disrupted by Windows dramas around updates, viruses, and mysterious background services. Never going back to Windows for audio!
Connections: Gigabit Ethernet connected to my old Logitech (Modwright modded) Transporter, which is mostly connected to a Shiit Ragnarock integrated amplifier which runs speakers, and Audeze LCD-2 headphones. I also listen at my ethernet-connected iMac via Fostex headphones via to a Dragonfly Red (MQA) dac/headphone amp. Not serious listening, but nice to have when working on the computer My “big” stereo system is also connected to the Transporter analog outputs. That system utilizes Magneplanar 1.6qr speakers, bi-amped with a pair of Citation II tube amps and a First Sounds preamp. That’s the system through which I play mostly classical albums on vinyl, probably 60%, with the remainder being popular music and the occasional modern digital classical album via Tidal on Roon.
So to answer your question, I’d say about 5 years running Roon, and the only big change was moving from Windows 10 to ROCK on the same hardware. I’m a huge fan of the interface, the information and insights into the music as an added value, and the graphic controls on my Android phone or my Apple iPad. The thing I like least about Roon is finding specific classical music, both in my own collection and via Tidal. Searching for the same work across different soloists, conductors, and orchestras should be straightforward, but it’s often incredibly difficult. When I ran Logitech Media Services, I organized my own digital files by composer and by work, mostly ignoring albums. Roon is very album-oriented, so pulling out works is not very easy.
Hope you enjoy your journey!
