Jadis amplifiers: rolled off treble?

Chris, which one have you heard?

I don't get this impression, in fact, the opposite, but not in a harsh or bright/shrill way. The words I most use to describe Jadis are romantic, sweet, and musical (probably more of these three than it should be), they're also pretty upfront and engaging. But, as with anything else, with the right tubes, ancillaries, and room, I don't doubt your assertion that things sound dark.

Trelja, I have heard the JA 200 and the DA 88 Signature.

Not trying to sound cavalier but if the music sounds more pleasant then who cares if the amps are rolled off? I have 3 of their amps and what they all do that I love is midrange. Rich, lush, warm midrange.

Loki, do you think they sound rolled off in the treble? My ears say: yes.

Chris, are you using one with your sound labs? If so, it would explain the high freq. roll off. A lot of tube amps without a tertiary feedback winding will roll off the highs. I agree with Loki1957, but not on electrostats. 'Stats need the power in the highs, not the lows. For your Soundlabs, try a Mac 275 or and EAR 509 or the new Cary that uses 4 kt88's as all of them have the feedback taken off of a third winding which exhibits less phase issues from the capacitive load presented by the electrostatic speakers. Those amps may not have the power you need, but work fine on a Quad 63/988/2908 ect. I am sure that there are others out there. To put into perspective, my EAR 509 (100 w) just cruises along with the Quads, yet the Quads bring my ARC D 250 to it's knees (250 w). I haven't tried the EAR 509 on the A-3's as of yet as I have a repair issue needing to be dealt with. Presently I am using Parasound JC-1's. I have a Defy 7 that is just magical (although tilted towards the mids) on cone speakers.

Ps: Sorry for not having gotten back to you before. I've been slammed at work, and income taxes were just due here in the states- ugh... Feel free to email me about your A-1's as I have just recently purchased a set of A-3's.
