Despite the religious wars going on here, I'm going to say that having a properly calibrated sub hooked up to your two channel is going to make more of a difference than what might (or might not be) a marginally better DAC. Just use the digial outs and let the receiver handle it.

Also, those pictures are absurd large and really, really annoying. What a surprise.
