Thiel CS 1.5 vs Linn Katan

No experience with the Linn Katans but I did own the Thiels for a while. On the plus side, the Thiels are attractive, one of the few speakers my wife liked, and very easy to place. They are extremely detailed. One of those speakers people will say "hearing things I'd not heard before on my cds." Beware though, if the recording is not well engineered it can be grating. The Thiels are also cool and thin sounding with very little bass energy. Their lack of warmth is what prompted me to sell mine for $700.
Check out Meadowlark Kestrel Hot Rods. Similarly priced, and sized but a very warm sound. Good luck.

I owned the 1.5s, pre Revel M20s and Harmonic Precision, Caravelles. 1.5s do not equal sonic nirvana, that's for sure, but you're heading in that direction. Like Tim, I found them to lack warmth, as well. They do have phase coherence to die for, great for jazz and vocals. Top is chilly and you need a sub. peace, warren

I would think they are entirely different sounding speakers. I have some Katans, never heard Thiels. I read that they sound just as Timrhu has described. Katans on the other hand are rythmic and soft on top, not so detailed.
What is your amp/other gear?
