I have a mid-end setup (B&W 703, Rotel RA-1572) and I'd like to make good use of the USB audio from my amp.

The DAC from my amp seems decent, so I'd prefer a single box without the need of an external DAC. 

Can you clarify?  Do you mean that you want to send USB audio to your amp and utilize the DACs in your amp?  If so, any of those devices will do that.  How do you plan to control them?
