Amplifier recommendations for Infinity 2500 speakers?

[ChefE]

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?

Here is the tech sheet for them:

An amplifier with at least 100W would seem to be appropriate. The tweeters are probably blown, causing the muddy detail lacking sound.

They shouldn't be lacking in detail unless something is wrong. GerryS suggested the tweeters are blown. Do they have a fuse on the back near the speaker wire inputs? If that is blown then the tweeters won't work. They may also need to be recapped.
