Step-up from Plinius SA-102?

Inpieces -

I tried e-mailing you through Audiogon, but I think it bounced.

Anyway, first off that sounds like a fascinating speaker you have there! Sort of a super-Kharma with deeper bass, but low efficiency. That low efficiency makes me think that, if there's one area your speakers could use a little help in, it's dynamic contrast.

The big electrostats I sell, Sound Labs, have a similarly low efficiency (though it's improved a bit of late). So I'm always on the lookout for lively-sounding amplifiers that don't have any grainyness (which the Sound Labs will reveal). An excellent amplifier in this respect is the Parasound JC-1, which is genuine competition for other solid state amps I sell up to twice its price. The JC-1 also works very well on non-electrostats that could use a bit of help with dynamic contrast, such as Maggies. They put out around 1100 watts into the 4-ohm load your speakers present (according to Stereophile's measurements).

There are plenty of JC-1 dealers so chances are there's one within reasonable distance from you who'd be willing to arrange an in-home audition. If you're within several hundred miles of New Orleans and don't have a local dealer, I'd be willing to drive a pair over to your house for you to try.

I'd be happy to take a shot at any questions you might have.

Best of luck in your amplifier search!

Be careful what you wish for. Too much "attack and control" can certainly be fatiguing, as you found out when listening to the Krells. I think the Krell monoblocks are great for a speaker that is difficult to drive, but in a dynamic speaker, it can be too much of a good thing. I had Krell FBP350 MCX's in my system and it was a little too much. I switched to Levinson 436's and for me it was just right. Detail and
accuracy without the fatiguing edge, musical bass without so much boom, just a touch of warmth, wonderful extension, snapped the whole system into place, etc. etc. etc. I encourage you to give them a listen.

I agree with Duke and Rsbeck.

The Pass is a good suggestion.Also consider the Edge NL series,Plinius SB300 or Halcros.Lamm M2.1/2,2s?

I think Duke nailed it, as usual. I have owned Krell before. My favorite was the older KSA 250. I had it for 7 years. The newer ones sound a little sharper to me. Lately I have been listening to the Parasound JC-1's and am very impressed with them. No listening fatigue. These would be over 1000 watt monoblocks on your 83db speakers. I think it would be a great match, try to give them a listen.
