I think there really are only two digital formats worth considering for such a component. PCM (a.k.a. "Redbook CD") and DSD (a.k.a. "Scarlet Book" SACD).
I'm still not really sure I would use one, though. Storing thousands of discs really is no trouble with products such as www.ujws.com available.
Besides, I like to have the liner notes by my side when I listen to a piece anyway.
Some folks might like such a component, though. You might want to chat with Ron Sutherland. He designed a tube preamplifier / DAC with USB input, thereby giving music download fans a high-end solution to get their tunes from the internet to there audio systems.
I realize that this isn't the same as what you are considering, but I do think you may be trying to appeal to the same market segment as Ron has. I don't know if his product sold well or not. It couldn't hurt to ask.
