Best amp to power Krell LAT 1000s? Krell Evo One, 575, Momentum, ASR Emitter II, MSB 203?

I have a pair of Krell LAT 1000's along with the Krell MRS and am looking for the perfect amp to drive them mains.  Have not been able to personally evaluate whether the Evolution One's construction is so matched to the LAT 1000's that they would be better than the new Krell 575's, Dan's new line (Momentum 300s) or perhaps the ARS Emitter II Exclusive (Blue) or the MSB M203's?  This is my condensed list of choices, though I'm enjoying the selection process and won't rule out new contenders.  Any input is appreciated.  My taste in music is wide ranging, from classical, to jam rock, to country, excluding only "death metal."  I'll probably be building out a new room for this setup at some point too.

Best, Justin


Pick your poison. My suggestion would be to look at the ones with the most Class-A bias, as from reports the LAT’s can be a little clinical, more Class-A the better to counter this.

The ASR uses Mosfets, and this "could" be an indication of limited current drive as tested by Stereophile. Doing 285w into 8ohms then only 128w into 4ohms.

" The bottom trace was taken with both channels driven into 8 ohms; it stops at 285W (24.5dBW), which is where the amplifier shut down, not where it clipped. Subsequently tested with both channels driven into 4 ohms (middle trace), the ASR shut off at 128W."

Cheers George

Hi George, hope this thread isn't too old for a follow up.  I took your advice, revised my searches, and pulled the specs on a few more amp choices to power the LAT-1000's: Dan's Momentum M400 monoblocks, or Burmester's 909 Mk5 (can only source one at the moment, but ultimately would get a second).  Didn't know if you'd heard either of them by chance.  Been saving my money since our last exchange, and have a little more room in the budget.  :)

I ended up with the Burmester 909 MK5... It's entirely awesome - fast, detailed, refined throughout.  And just the one unit, wired stereo, will blow you out of the room (with the two Krell MRSs).  Still wonder about the M400s though.
