Amp for Usher BE-20 ?

Hi all,
Usher Be-20 owner out there, what amp you use to drive these beast ?
I have these speakers for couple days now - these have Diamond DMD tweeter. Still listening with Krell KSA-50S
Amps at hand including Atma-Sphere MA-1 and Cary 805C.
Pre-amp is Cary SLP-05
My listening habit is not too loud, and this Krell 50wpc is ok (only first light bias lid). But somehow I hear the low freq quite missing
I will rotate amps to test it out - Not sure if I need something with 200wpc, SS or tube ?
The DMD tweeter is somehow bright to my taste (got use to softdome tweeter, need time to adjust my hearing :)
Do you think tube amp will help smooth out the HF? I might try Cardas Ref cable to soothe the DMD ?
TIA

We represented Usher for several years and, in our experience, they performed best with high current, slightly warm solid state amplifiers such as Pass Labs, Simaudio, and Ayre.

Thuan98, you hardly have any break-in time on them. Give them a few hundred hours of play before you start worrying too much about how they sound.

I used to have Usher Be-20. I think it also benefit from amp with higher damping factor. Something like Lamm M2.2 which has enough wattage to play as loud as I need does not control the bass quite as well as I would have like. Lamm's damping factor is a bit on the low side at 82. While you don't need amp with damping factor in the thousands to ten thousands like Soulution or Karan, damping factor of a few to several hundreds probably would be enough.
