Do yourself a favor and look for a pair of Tyler Acoustic Linbrooks--4500 new. It was the best thing I ever did. My best friend has a pair of Martin-Logans and I left him crying and angry after hearing the Linbrooks for the first time. We went to an Avant Guarde Duo demonstration, that's a 12,000 dollar speaker roughly, and me and my buddy thought the Linbrooks were nearly 90% of the Duos. The Duos had more "air", more ability to separate instruments in the soundstage, and it had a touch more low-end. But both speakers were refined, highly detailed without edginess, and threw a wide soundstage. I bet you can find a pair here for something like 2000, check out their website.
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.
