Thiel 2.3--bright or harsh ?


I have a pair of Thiel 2.3's running with a Krell integrated-KAV300i and a Rega Planet CD player. With a great CD the sound is wonderful----but put on a "questionable" recording and they sure sound bright or harsh. I heard about an upgraded driver for the 2.3's but did not arrive yet. Anyone have any experience with this.. Will the new drivers do the trick---and/or is there anything else I can do get rid of some of the brightness.

Gjrad is right. Don't ever expect Thiel speakers to sound lush and romantic. The 2.3 will always be a struggle for you unless you like a clean, slightly "whitened", slightly lean sound - but teaming the 2.3 with Krell is not likely to work well, and will more likely tip, what I have described above, over into brightness. Perhaps a 50W tube integrated, or a change of speakers will be best in the long run. If your budget isn't ready for that for a while then experiment with some MIT cables by all means, but I feel you will have to deal with amp or speakers eventually.
I do agree all the above comments on the Thiel speakers. If you are looking for lush or warmer speakers, then please check with something else. Speakers sould be the center of your systems, but maybe tube pre and power amps could do the job too. Tim
I have Thiel 3.6's - they aren't bright in the least but I've got lots of ss power and warm tube amp (classe ca200 and cj pre). I've also got meridian digital which isn't in your face at all, very unfatiguing. They are the most tonally correct speakers I've ever had in my room, also the most open presentation for a dynamic speaker. The Krell might not be the right match, I've never heard that combo though. Classe is an excellent match, I've heard Aragon is also, a tube preamp IMO is a necessity. Before you spend lots of money on cables I would try to audition a different amp if possible. One thing for sure even on my system a crappy CD sounds like crap! Thiels don't lie! Good luck.
Hi Pops. I have Thiel 3.6 driven by the latest Plinius SA250 in one of my systems and they do sound great (and not at all bright - as you say. But the 2.3 is not in the same ball-park and tonally leaner IMO. I feel the Plinius is better than either the Classe or Aragon, but with the 2.3 I would tend to use a tube power amp.
Follow up response to "Pops" my son has an Aragon 8008st and had for a short time a pair Thiel 2.3s, same problem as with the Krell, too bright. It wasn't a good match. With Thiel 2.2s his current speaker the Aragon works much better but the 2.2a are a different speaker. Be careful when matching a tube amp with the Thiels especially one with only 50 WPC if you want any kind of a bottom end. The mids and highs will be ok but you will have very weak bass and the whole speaker will sound lean. My Jolida 502a did not work as well as a SS. If you go tubes look at AR or VTL etc but at least 100 WPC.
