All Digital System Questions. Compatibility?

I have an Exogal Comet Plus DAC that I was thinking of pairing with Bel Canto 600 Monoblocks without the use of a preamp. Is this a good match Specification wise. I hooked up my Parasound JC-1 monos to the Exogal and it sounded great but the volume control needed to be pushed very high to go loud. I felt like I was only using half of what the amps could really provide. I have a Parasound JC-2 preamp that i can leave in the chain but I'm trying to simplify. The JC-1 amps take up too much space and that is the reason I'm thinking of going Bel Canto. I play music through my Macbook Pro and Arcam FMJ 23 cd player. Any thoughts?
