I am a hardware nerd and a bit of a carpenter, and I have been wanting to build my own surround sound system for a while. By build it, I mean from the component level up. My own amplifiers, pass filters, toroid windings etc.. but while I cant/dont want to do is build a decoder / DAC. My TV is only hooked up to a Mac Mini and an original Playstation 3. It would be nice to be able to pull the plain 7.1 digital audio as well as TruHD and DTS-HD out of the HDMI, but I would be willing to do something else, IE USB3 for the MacMini and optical digital for the PS3.
tl;dr: Anyone know a good HDMI DAC with a high bit width and 7.1+ channel output?
