Thank you for your input!
Tweak1, I share your thoughts about Maggies; I appreciate what they can do, and while I have listened to the newer 1.7i, it still does not tick enough of the audio boxes to keep me listening for hours. I have yet to hear the Emerald Physics, they are an interesting design as I like OB-type speakers. Intriquing that they have 'stat-like qualities.
Mijostyn, I hear you on the Sound Labs design; their dispersal pattern seems to be what most 'stat lovers crave the most, and the 845's would be amazing. I really appreciate your heads-up on the loose panels as I have toyed with assembling an Acoustat pair from parts, as well.
ct0517, It would be a lot of fun to listen to your 3's vs. the rebuilt 57's, as Wayne's builds are said to be as good as Quads get, and produce bonafide bass. I have wanted to listen to a good pair for years...Those B&W electrostats are fascinating, I would welcome an opportunity to hear them sometime; who would have guessed B&W ever built 'stats?
clio09, Congrats to you for figuring out a way to use the Servo amp with your Model 2's; it's hard to beat the qualities of good tube amps. If you could share about how you achieved better dispersion on your panels that would be helpful, as that is the area I have had questions about. Also, I guess it should be no surprise that Roger Modjeski designed ESL's, as well as top drawer amplifiers; an amazing guy and he is missed by many. Sanders Sound electrostats are another speaker I would like to compare Acoustats with, however, they seem to be fairly rare in number.
All things considered, it seems as if Acoustats still have some life left in them, and the fact that the high voltage interfaces can be rebuilt is very encouraging. I have read that the 1+1 and 2+2 models have the best imaging, which, along with speed, is what I am looking for the most.
Thank you for all of your replies so far!
