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

I run my BE-10 with MUSIC CULTURE MC-811 and MC-601 pre-amp. Truly amazing. MUSIC CULTURE has been created by the founder of MBL. Same sound without the price's extra zeros... Even if it's not cheap at all! The MC-801 power amp is also damn good for a low price, even better than 4 times more expensive electronics.
The sound is emotional and i didn't find many electronics able to do such things with so much evidence...
do you think a rogue magnum chronos would power these speakers? i have the 120 tubes rated at 100 watts.
I would like at the Purity Audio Class D Tube Hybrids or the Clayton M200 or M300 if you can swing it.
They need power! Try the Merrill Audio Veritas mono Blocks with a tube preamp like the Purity Preamp.
big bump: Hegel h360 drives the big ushers loudly and smoothly. My room is 17x27x7' but you can tel when a speaker has enough power or when it's not giving it up and these speakers sound like they're holding nothing back. I've tried some 'hi end' speakers only to find I couldn't afford the electronics necessary to get the best out of them so I was relieved to hear the BE-20's sound so dynamic and effortless. I think Usher might one of the best kept secrets in audio.
