I have listened to Audio Physics for the first time last week on a Cary amp. I have all solid state equipment and it was the sweetest sounding for classical music I have heard yet. If set up properly and can listen on axis they have a wide and deep soundstage. The speakers I listened to were not even set up the way Audio Physic recommends on their web site, which not many people can do, and still sounded well. I listened to the Sparks which are on Audiogon for approx $1600. They won't knock your socks of on bass but otherwise very good. I also have a friend with tubes and he has the soliloquy which he loves. I have not listened to them yet. Happy hunting!
