Do Thiel Audio CS3.7 Rock?


I currently have Esoteric MG20 speakers and while these are great on some types of music they really don't rock, just sound a bit too polite.

I hear a lot of good things about Theil CS3.7 speakers but more than a few reviewers mention the lack of bass. As it's difficult to get a demonstration here in the Netherlands I would need to go to the UK so some advance tips would be appreciated.

Chosen speakers would be paired with an Ayre V-5xe amp with K-5xeMP pre and Marantz Pearl CD player.

Thanks

I disagree with Stanwal,

I have heard the 3.7's many times and they have never been what I would call bright by any means, they are very natural and a little polite to my ears. They can have excellent bass, but they require huge amps to get it (best I've heard so far was with the big Jeff Rowland mono's.

That said, though the bass was tight and went deep, not sure they would rock. A speaker needs to have high output and bass to really rock, I loved my Escalante Fremonts and now my Wilson Sasha's as they both are efficient and have high outputs, especially when paired with lots of power. Not sure how well the Thierls would do in this area.
The best speakers for Rock and also Classical and Jazz to my ears are the Odyssey Audio Kismet Reference Floorstanding Speakers. They are simply amazing. My rock taste goes from Metallica through Pink Floyd and everything in between. They never, ever disappoint.
The Thiel 3.7s are not bright to me. They do rock, and i have heard them with your preamp (only not MP) and amp, they were very nice together.
