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

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.
Thiel 3.7's, which I own, are speakers for those who prize transparency over other qualities. They are most definitely not bright and I think that using them with less than 200-250 wc high current amps will not allow them to sound their best. If you are asking whether they rock, it seems to be you are asking a question that indicates these speakers are not for you. In the same used price bracket I would look at Wilson sophia IIs for bass dynamics.
In Europe I can get the B&W 802 Diamond for about the same price as Theil and know these do rock. I have never heard GamuT speakers but they are a bit more expensive. Has anyone else heard them. I'm trying to get a short list before going to audition as it would probably be in the UK as prices are lower there.US speaker like Wilson and Vandersteen are stupid money here
