If you're looking for a multi-channel dac to go after an active crossover, there's a ~$3k price gap between the common options of the miniDSP stuff and the Exasound e28, with very few options in between. It would be great to use the half-way decent dacs in a lot of fairly cheap multi-channel receivers. Is there a way to use Jriver or any other piece of software to pass 6 channels via USB or maybe HDMI to a receiver for the DA step?
