I have to agree that Cardas cables are a good match for Thiels. I have a pair of 3.6's and auditioned several cables before deciding on Cardas. I've also found that my Thiels are very placement sensitive. Moving them even very slightly produces noticable changes in their sound. Mine took quite a bit of patience to get them positioned right. Having said all that, I've never been happy with their sound when listening to poorly recorded material. They seem to be very unforgiving in that respect.
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.
