power amplifier suggestions with BelCanto Dac3

Sorry Mods I slipped and put this in the wrong forum.  

The natural pairings with the Bel Canto DAC3 are the Bel Canto power amps. If you're looking at a stereo amp instead of monoblocks, the REF150S or REF500S will work very well with the DAC3. The two amps be the same from a quality perspective, just differences in power. The REF150S will give you 60W per channel into 8 ohms and 120W into 4 ohms. The REF500S will give you 200W per channel into 8 ohms and 400W into 4 ohms.

I have a DAC 2.5 paired with a Ref500s....they are great together, but magic really happened when I added a Primaluna Dialogue Premium preamp... 

I appreciate the offers to consider. I should note I have a full shelf available and no need for a compact power amp. Not that I rule the siblings out. The current Bel has to share a bunk so it worked great for me that way. I have a Bryston 4B connected to get by. Not a match I'd want to live with long term.   

What don't you like about the Bryston and what sound reproduction characteristics are most important to you?  Great DAC by the way.  If there's any way to upgrade to the VBS do it.  The difference between stock and VB is not small.
