Bob,
I have both a Denon AU-300 and a Denon AU-320 in my collection. I didn't recommend either because your budget was more than these sell for. The AU-320 will work just fine. I really do think the Bob's Device SUT and/or the Silvercore SUT are better sounding, but are more money. You should be fine.
