Your ''best kept secret'' speaker choice ?

PSB 500- with great "best buy" reviews, this baby is still underrated. For anything in its price range, it has amazing clarity, presence and depth.

Reimers. For less than $4000, the Wind Rivers are amazing in every respect, and for less than $6000 the Tetons are that much more so. If you can manage a way to hear them, do it!

ESP . Fairly well known but simply incredible.

World class mid/tweeter ribbons. Sweet, dynamic, detailed, airy, effortlessly loud RIBBONS! They're Swiss, and not very well known/visible in USA, but read the reviews.

The newer aluminum "C" series has been getting a lot of attention recently (Stereophile Class "A").

I would look at Source Technologies, the owner/designer John Sollecito was the "J" in JSE Engineering in the 80's, and he also developed the highly reviewed "Harmonic Recovery System" He's been building speakers for a solid 15 years - all price ranges.
The website is not one of the best, he doesn't devote much effort to it, nor does he advertise or attend shows.
