Thiel Owners

The sound clarify in the second one is far from natural and has much distortions. I like heavy rock but would not measure speaker characteristics based on that kind of music (even some early Black Sabbath recordings are better for this purpose).
There is no way to reproduce such recording naturally so it is hard to judge on speaker quality for that kind of recording, in contrary to the first one. 
Thiels never fail to reproduce naturally
human voice, in particular. 

Then you may prefer Wilson Audio speakers.  For my taste they sound coloured and a bit aggressive (nothing to say about the difference on price).
