Jerry - if the piece of equipment you are referring to is a SonicOrbiter SE, run in its RoonReady mode, I can tell you from personal experience that it should not degrade your sound. In fact - because of the benefits of RAAT that it provides - your digital music may sound better than it ever has before. I’ve been an audiophile on a budget for many decades, and it’s the best digital sound I have EVER heard, and I’m including music from my CD player in that judgment.
Can you introduce noise from another electrical device? Of course. But I don’t hear it from the Sonicore SE’s supplied linear power supply. If that is a concern though, buy their “international” PS, which is really an iFi IPower. It’s very unlikely you’ll get any noise problems from that.
There are those that feel that a wired Ethernet connection can introduce noise vs. wifi. I do not fall into that camp, have never experienced it in my hifi gear, and I’ve been using Cat 5 connected digital music streamers since 2001. But your mileage may vary.
As for the music itself, people talk about “bit perfect” all the time. But bit perfect can still be crap if the timing of said bits being passed between components is not likewise perfect, and is a major cause of jitter. The SonicORbiter SE - and ANY RoonReady Endpoint connecting by USB to a DAC - solves that. Your DAC’s clock will control all the timing of music movement between components, all the way back to your Roon or RoonServer. Honestly I’m not sure I can say I can hear the difference with my 16/44 music. But the improvement is quite audible in all my high res music.
So it’s prudent to be concerned. But IMO a well informed review of the issues may show that it is concern that is unnecessary. Your music will likely sound better, not worse. You may want to get other opinions on that. But I’ve shared mine.
