Good In-Wall Speakers?


I am looking to install speakers in the Living Room, Dining Room and Kitchen. I am looking for the best in-wall speaker which retails for less than $500/pair.

Most of the time the speakers will be used for background music, but I want a speaker that will still sound good if I decide to turn up the volume.

Size is not an issue. My main concern is sound quality.

Any suggestions?

Thanks everyone for the advice. Anyone heard the Paradigm in-walls? They are highly rated speakers, but I have not found a dealer who has them set-up for listening.

If Linn still makes their in wall speakers, they are well worth a listen (think they retailed for around $600/pair). I was looking for the Linn "panel" flat wall speaker a while back, but they had been discoed, listened to the in wall speaker instead and was very impressed with the sound. I did not want to hassle with the installation though.
