Unison especially on BF2 and up (since you get galvanic isolation) is a really good USB interface but that doesn't mean the source doesn't matter at all. Go even read Mike's thread where he says Unison out (from the Schiit Urd) to Unison sounds better than his streamer.The primary reason I'm asking about streamers is that the guy I bought my cables from said streaming from a computer sounds lifeless, and a streamer makes a huge difference in that regard. Granted, most of you are gonna see "cables" and read "snake oil"—that's fair enough, but selling cables doesn't make him a liar about everything else
Do people with a Bifrost 2 generally prefer a streamer even though that means using S/PDIF over Unison USB?
There still can be improvements from going to less electrically noisy sources. A cheap-ish way to check is to build a Rasberry Pi 4 based streamer and check. But a Pi 4 + iFi iPower (can use any 5v switcher with the Pi but the iFi has been measured to be lower noise than the cheap ones and it's not crazy expensive) did sound better to me than from my gaming computer.
Now I have a Pi2AES on order (I'm sure some fancy USB based streamers from Sonore or SOtM feeding Unison would be even better but those are a lot more costly than the Pi2AES).
This video might help: also iiWi Reviews has a bunch of good videos on Pi based streaming.
