I have a very basic question. I'm thinking about purchasing one of these. Question: I understand I can run my turntable to preamp to RCA inputs into the SurroundMaster, and then the RCA outputs to my AV receiver for 4.0 or 5.1 sound. And that's probably enough for me, but I see a lot of commentary about folks playing SACD through the SurroundMaster. If I play an SACD on a UHD, there would be no reason to pass that through the Surroundmaster via optical, and then out to the receiver, right? Because the UHD player directly to the AV receiver by HDMI is already decoding and processing the SACD?
