I own classe amps and JMlab Diva. I have heard Thiel 2.4 and there are some similarities to the DIVA. I have grappled with issue of too much treble. I have had KS3033, Au24 & Ridge St speakers cable for shootout with a friend. For my sys, Ridge St is best by far with the most detail, layering and all the right qualities. It was not bright at all and certainly not brighter than the other two copper cables. Au 24 was second: it emphasize midrange and was friendly for voices and vioin. It may work to your advantage with slighty roll off treble. Kimber has the strongest base and pretty well rounded and neutral. I really wanted to keep it because of the looks and the build quality. It sounded a little bit coarse comparing to the Ridge St Poiema.
As for too much treble, try less toe in, check the room, maybe power conditioning may help.
You have to try in your own system. Buy used, keep the one you prefer.
