Can someone tell me if this would work and sound decent..I want to power my 2 rti12's with a receiver pre outs to an Adcom amp. I had originally wanted to just use a 2 channel receiver from Harman Kardon but since I want to use the digital output from my computer I was thinking about looking into a cheaper 5.1 channel receiver that could accept an optical input. There are tons lying around on ebay that I could pick up for less than 200 bucks.
Any thoughts about what I could change improve on. I was thinking about getting a DAC but dont know of any good external ones that can be had cheap. I really dont know much about external DAC's so I dont know where to start looking..
