Perhaps posted in the wrong place? Building a DT and speakers to go with tv for HTPC. MB Gigabyte z77m-d3h with 3570k. Old Altec VOT speakers (no cabs yet). I want to use Minidsp's (for crossovers) and their digital miniamp to electronically cross and bi-amp each speaker. They have units that accept both analog and digital inputs. So far so good. I have a Samsung flat screen with optical 5.1 out. I will play music using cd, and flac files, and movies from tv,dvd, and files from the DT. To tv via HDMI out of MB. The big issue seems to be getting sound to the speakers as anything other than 2.1. 2.1 would be fine for music but the movies need 5.1. I can use a software decoder and analog the channels to the Minidsp (there are several choices of number of inputs and outputs), then it will re-convert to digital and back to analogue (at the miniamp output to speaker) again, but this seems ineficient and lossy and I would prefer to use their model that accepts digital in. Looking for a clean way to get 6 digital channels (on coax) coming to the sound system. I don't want to run an HTR or other amp, as I will be amping in the speakers, and I don't care about FM tuner. BTW the MB has s/pdif out if I have to use an external decoder.
