CD as well as DAC technology is extremely mature these days. Its safe to purchase an el' cheapo model. When you hook up the CD player using the digital inputs you are going to be using the DAC that is supplied in the receiver anyways.

I'm not sure what the going rate is on multi-disk CD changers , but considering how there would little demand for them and more "niche" products, they might not be priced competitively as we might like. I'd be interested to see what you end up with.
