I currently have a Yamaha RX-V465 from about 3 years ago. My mains are Definitive Technology studio monitor 350's, center is pro cinema 1000, and sony sub and surrounds. I am looking to upgrade to a mid range receiver ($700 range) I use a Play Station 3 for my dvd player. I like the sound, however it's just not as powerful as I would like. Is this possible with my speakers? If so, what receiver do you suggest? Any comments are appreciated!
