Going the digital route will make a huge difference IF you have the equipment to back it up. Having a kick a$$ processor means nothing if you have crap equipment. This goes for cars as well as home theater.

sorry to dig this up again, but how do u adjust the volume if you use H700 optical input from the PC?

you adjust it with the RUX-701 controller, just like normal.
