Hello AK. I have a set of Infinity 2500 speakers. I've searched the Internet for information and specs. Turns out there is not much info or peoples experience with the 2500's. Found out they are 4 ohm and rumored to have been created specifically for a Southern California chain of stereo shops back in the day. The speakers have a unique sound that I'm having difficulty finding words to describe them. They come off muddy and lacking detail, and for some reason I find myself intrigued, almost addicted to their odd output. Currently they hooked up to a temporary system for experimenting; a Dual c830 and rotating receivers: Wintec R-1120, Sansui 8900ZDB, G-7700, QRX-777. Anyone have experience or information regarding the speakers? What amplifier/ receiver would be a nice match for the Infinity 2500 speakers?
