I want to build a HTPC but have some questions on audio amplifiers. Is there an amplifier that exists that has coax/optical inputs and has 5.1 or 6.1 or 7.1 analog speaker outputs? The sole function of this device would be to just take digital data from the optical/coax and demux it into 6, 7, or 8 different channels. I'd like to do the signal adjustments from the HTPC. so this device I'm describing is really just a simple 6, 7, or 8 channel amplifier that happens to have a digital (optical or coax) input. Obviously, the analog channels wouldnt all have the same specs since it would be in use for a 5.1 or 6.1 or 7.1 speaker setup.
My plan would be to not have a receiver, just a HTPC, and I would sit this device Im describing behind the TV where my wall plate is where all my speakers terminate at. Or, if this device Im describing is just a 6/7/8 channel demultiplexor that feeds powered speakers that would work for me as well, but I would prefer the former.
Surely Im not the only one to ever think this up?
