In addition to my home theatre, I have recently gotten into two channel audio with a new 40 WPC integrated amplifier. I am using this to drive Definitive Technology BP8's. They are rated at 91db sensitivity and are rated to handle 20 -200 watts/channel. This setup is very clean and sounds good to me but I know that I can pick up a used 125 WPC amp on ebay for $250 - $300 and use my Rotel Integrated RA-01 as a preamp. The 40 WPC amp will drive the speakers to a very loud volume but my question is whether I can expect better sound with more power or is this a waste of money to prove the misconception that more is better. Thanks for your feedback.
