Totem and Bel Canto?

Right now I have a NAD T747 and a pair of Rainmakers on Atacama stands and I would like to upgrade my sound. I am leaning towards either buy a NAD 275 power amp and running the speakers through that or a Bel Canto Integrated (either the S300iu or C5i). Anyone have experience with either of these? Not sure if it matters but I only have digital material(no cd or vinyl) so I was thinking that the Bel Canto might have the better DAC.
