So, I'm sitting here (for my second night in a row) a little buzzed listening to everything and anything I can find out of my Cat 12 (2 channel) system and I'm still thrilled by it! I have no treatments, just a bunch of carpet and soft sofa material, and I'm still very happy! Two Cat 12's and two Sub-M's and I'm probably overcooked (and better for it, lol) on bass. This whole area turns into a club-like environment when I want it, and when I just feel like listening at intimate levels and "feeling it" I'm plenty happy. I have to say, these things still make me happy! Mark has done a great job, and these are, in my opinion, very diverse. I can crank the heck out of them or just sit back and listen to them in a relaxed environment and enjoy them to death. They've brought tears to my eyes more than once, and put chills down my spine at least a few times. My old Paradigm Studio 60s were great, but they are not missed, lol. This is about my one year anniversary with these speakers and I'm still very happy I bought them (thanks Mike for the great deal).
