I run a Bryston B60 with my AP Yara Evolution Bookshelves. Its a fantastic match IMO.
When demoing, I also heard them through a McIntosh MA6500. It was equally good IMO. Different, but just as good.
Relatively speaking, the B60 is more forward, detailed, and leaner. It sounds a bit faster. The Mac's soundstage is set back further, smoother, and warmer.
Both are very musical and involving. They're just different. It all depends on what you're listening for.
