If setting up for two channel only...I would get a good two channel preamp and use the analog outputs on your 596. Adcom has a nice passive/active preamp that I was thinking of pairing with my 596 in a second room. I've heard the 596 in such a setup and was floored by how good it sounded. I've never heard the Adcom but thought about giving it a try so I'm not saying get an Adcom. There are a lot of great two channel preamps out there.
