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.

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.
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.
Von Schweikert VR-4 MkIII.Magenepan 3.6/R ribbons and full range panels. Both are about $4k new.
A company from Belgium, specializing in cello manufacturing has designed a series of speakers called EHS. These comparitively diminutive floor-standing speakers reportedly use no crossovers, but utilize the fabric cover, which is non-removable except by the company. So, if driver blows, back to Belgium. I owned a pair of "Tenors", the company's flagship, for about two years. Holographic, musical, romantic, but rolled off. For string music, especially small ensembles, the presentation was fabulous. Lay a rock or funk jazz track, though, and the heart of the energy was lost. Costs for these speakers (I'm not sure if they are still being made), range from around $600.00 to $4800.00.
By the way, the cabinet work was top quality and a joy to look at.
Nobody's reading correctly. The 2 key words are BEST and SECRET. Most of the above ARE NOT secret and maybe not the best. The correct answers are: VMPS(ribbon hybred $1600 up new)the Australian lab Ambience (ribbon hybred $6K new). Possibly the best kept secret is the gigantic line from the little known french lab called Cabasse. I'll know in 3 days.
