I've heard the clue speakers and they're quite good for the price. I think they excel at Rock, Pop, Electronic etc. And Lars at Sjofn is just a blast to talk to. Spent a couple hours on the phone with him talking about speakers, the Seattle music scene, Jazz, Nordic Jazz and completely off topic subjects.
Instead of the usual flamenco guitar, Diane Krall, they play at audio shows ad nauseum, he plays Nirvana, Alice in Chains and Metallica.
Even sent me CD's to listen to free of charge without purchasing anything from him!
If you live in the VA/DC/MD area he has a fantastic rep that has a whole line of bang for the buck audiophile products (including The Clue) he'll haul to your home to listen to in your setup.
His name's Mark and email is mark@wellpleasedav.com. He traveled to my home twice already (an hour each way) just to bring various gear to listen to. I couldn't recommend him more highly.
