Well, stand-alone DACs are pretty hard to find any more online unless I go to ebay. But they're usually over $1,000, which just doesn't make any sense considering even a cheap receiver will still do a good digital to analog conversion.
Though, looking for DACs I did happen to stumble across a lot of surround sound processors, which typically are DACs. I think after I get 4 of these A500 behringer amps, I'll try getting my hands on an actual processor to replace my receiver. No point in keeping the receiver if I ain't using the watts. I'm glad the Behringer is so cheap compared to other amps. I thought I'd have to go buy some expensive $1,000+ amplifier that's only 50 watts per channel or something equally moronic.
