I have listened to the Anthem 225 a few different times, with NAD CD players and Paradigm Studio 60/100. I think the 225 is a much under-rated piece, or at least doesn't seem to get a lot of press. But most who hear it think it is a fantastic sounding amp. I am one of them. It has the Anthem sound to it which I feel is very clear, maybe a bit polite-not in any way offensive, yet has excellent bass capabilities when needed.
I ama bit biased about Anthem as I own several pieces of their gear-AVM30, MCA 20, PVA 2, TLP1. Just good sounding gear, great build, and the 225 is a very good buy, even new.
I have also listened to the Exposure gear and like what it does too. The Anthem just may be a better value, but it is up to your ears and wallet! Enjoy the music, Tim
