Don't think I'm crazy but...

I think I am wanting to replace my Thiels. I have the CS2.3's in a system I recently purchased a few months back. I started out with a set of B&K Sonatas driving them and kept blowing fuses/running out of power. My buddy talked me into buying as he puts it "more balls" so I bought a Bryston 14B SST which came rated at 969 watts pc @ 4 ohms on the run off sheet. Plenty right. Well I still don't think my system is "loud" enough. My other components for refernce are a Denon 2900 SACD player and a Denon AVR 3805 which I use to drive my other Paradigm speakers (I think the center channel is a cc570 or something). My room is big (35x25x8) which doesn't help I'm sure. Anyway someone else told me I need to be looking for more effecient speakers like say in the upper 90 or around 100 db's not more power. Any thoughts or recommendations? Sorry I'm just getting tired of throwing my money away. The Bryston guy told me I could drive anything with that amp but I've had it clipping out if I'm not careful. I guess I'm sort of deaf, wonder why eh?
