What amp sounds best with the B&W 803D Speakers?

I bought the B&W 803D Speakers after hearing them paired with the McIntosh MC 402 amp. Definitely, I thought the sound was excellent. Though I have not heard them paired with the Classe amp (anyone hear the CT 2300), that is suppose to be a great match. Did anyone hear both, and what are the similarities and differences between Classe and McIntosh? I appreciate the feedback.
