@debjit_g I may try another motherboard at some point, one I'm using at present was chosen by original streamer builder. He and the subsequent owner both compared to many off the shelf streamers, only the Taiko Extreme bested this custom build, both purchased the TE. Both compared when this custom build was using HDPlex internal SMPS and outboard LPS. Since I purchased added JCAT Optimo to power it, far superior to HDPlex and the outboard LPS they used.
The Euphony subscription model is kind of a bummer, but for just over $200 per year I don't need to screw around with diy OS. Convenience is nice and SQ is superb, never had V3, but V4 has many nice reviews.
The usb boards you mentioned are the ones I'd go for, no sense in going for less than best here. I went with JCAT net xe board vs the lesser JCAT net board, previous owner of streamer had both available.
Powering OR and JCAT net card with Uptone JS2, choke based ps vs cap lps, sure that's not hurting OR and JCAT performance!
Sometime down the road I'll probably try out other boards, for now completely satisfied with SQ with custom build used as server only with the OR as Roon streamer via Sqeezelite adapter. Prefer over custom build streamer running Roon and embedded HQPlayer, custom build server duty only, HQPlayer Roon embed via OR, and custom build server only, Euphony Stylus via OR. Haven't even tried full Euphony Stylus on custom build, made a disaster of my local library on importing from NAS. Full Stylus via custom build using only Qobuz and Tidal libraries is fine interface, problem is I'm addicted to Roon interface and have too much good music in local library. Running full Stylus reportedly best SQ, have to experiment with this sooner than later.
