I would consider a bel canto dac 1 used $700 on the digital out of your cambridge otherwise I have only heard the audio refinement player... I wasn't to impressed and bought a rotel 971 for less money eith better sound . I believe that the MF would be much better as a stand alone. check out the review at onhifi.com for the MF, the Bel Canto and the Perpetual 3A another thought at $699 New..mmm I would definately consider using that 4se as a transport and take advantage of one of these upsampling dacs.. maybe that perp on a 30 day trial. have fun,
