Appreciate all your replies. The Ref 3.1 is my first choice, but the PMC also sounds oh so nice too. There seems to be little press about the PMC brand in the USA. The Ref 3.x have received many excellent reviews with some reviewers replacing their current high priced speakers with the Ref 3.1.
Yes, I've heard that the CDT can be bright. I've read a few posts where they felt the Ref had a roll-off with the lower mid dynamics. I thought I noticed that with some tracks, however, my demo session was rather brief with no A/B reference.
FWIW, the PMC was driven by all McIntosh mono amps/tube pre/cd player. The Ref 3.1 was driven by all BAT mono amps/tube pre/? cd. The PMC just did everything well like an excellent all-around player, but the Ref 3.1 displayed some amazing play.
The Ref 3.1 have some excellent reviews, but here is a post in favor for the FB1 http://www.positive-feedback.com/Issue25/pmc_fb1.htm
I'd appreciate more input please.
