Hi All - thought I'd check in after several months with these.
I absolutely love them. As someone who's owned speakers that retail for $30K+ (the Avantgarde Duos featured in my Avatar...and no, I didn't pay nearly that much), and many, many others at all price points, these arguably sound best of all! I listen to all types of music. This particular pair replaced a pair of Magnepan 3.7s (talk about opposites!) I'm using these with a Klipsch sub at low volume with the lowest crossover setting - provides a nice seasoning.
I've used these with a Hegel H300, but my real love with them is tube amps. I've tried a couple with great results. Tube selection is a little more difficult since these are so sensitive, but that makes me use the best tubes I can get. I listen to vinyl, CD/SACD, files, internet radio and even minidiscs - all of which are wonderful through these La Scalas.
The toughest part was moving them!
Mike
PS They were my first Klipsch speakers but not my last! I've already bought a new pair of Heresy IIIs to go with another system.
