I have to agree with fizgig, the Silverline Sonata's are superb from top to bottom. All the speakers mentioned here are very good and I've heard most of them but the silverline just disappear and let you hear the music.
Best Kept Speaker Secret?
OK all you speaker experts out there here goes. There are always "sleepers" or "exceptions to every rule or cost" in high end audio equipment. In your opinion what is the best kept secret or exception to the cost for the very best speaker you can buy for $4000 or less (Used). Your feedback will be greatly appreciated toward building my short list. Thank you.
