Ok, I've decided to go with the Parasound HCA-1205A 140WPC amplifier to drive my speakers. I've heard a million times that with the Studio 100's you need 200+ WPC, however lately I've come to the conclusion that the difference between 140 wcp and 220 wpc won't be worth the additional $800 I'd have to spend. Sure at insanely high levels during movies and some 2 channel music the sound might be a bit cleaner etc. but is that enough? If you have any STRONG opinions to the contrary, please let me know. Unfortunately I have no Parasound dealers around here so I can't test both of them in house without paying shipping and restocking chargers. So I guess the main question is, will the extra 80 wpc be such a massive difference that spending the extra $800 will be a no brainer?? If you're curious, my center channel is a Studio CC, I have a PS-1000 sub, and Eosone tower's for surrounds. I'm driving it all now with a Yammy RX-V795 85 wpc Receiver (for now, I'll use as a pre-amp with the new Amp) Thanks!
