Listened to the Solo 575's today ........
 

and I wasn't impressed, at over 22k (msrp) IMO, your money is much better spent on a pair of PASS labs.

Now I must say I listened through a pair of Totem Wind which in themselves are 'underwhelming' IMO but I was expecting the 'i-bias' of the Krell's to do more.

Anybody with opinions on different speakers ?

I have listened to the Krell Duo series and Solo series amplifiers with Krell pre-amplification on many loudspeaker brands and did find it very musical.

Heard these hooked up to a pair of KEF reference towers and thought they sounded pretty great... I'm thinking it was the totems
