Acoustat 2+2...Any users?

Have had a pair of 2+2's since '84. Used a Sumo preamp with the Sumo Nine power amp for years. Now using an Audio Research Sp11 with a Audio Research D250 and a Musitek 15 inch Sub crossed over at 100. Am going to sell after all these years. Just picked up a pair of Gallo 5LS's. You need a good front end and a tube or class A amp for these speakers. They are very critical - if your amps are sub par you will know right away - nothing is fudged. It really sucks to have good music that is poorly recorded as the speakers hide nothing. There is a narrow sweet spot but I usually am the only one listening so it does not matter. Room placement is critical and you should get the speakers three feet off the wall since they are dipolar. I am using Nordost Red Dawn speaker cable & had to turn down the high frequency adjustment on the 2+2's. Imaging and focus is pretty good. I will be listing them on Audiogon in the next little while. I am tempted to keep them but there is only so much room and have to deal with the wife factor. I listened to them for 30 years because I could not justify the amount of money I would have had to spend to beat them. I did not have to spend a dime on maintenance expect to dry clean the socks. I have just recently upgraded my front end and the time has come to move up. I hope they find a good home.

I have owned Acoustat 2+2 speakers since 1986 and installed the medallion transformers +C upgrade and use HIfi tuning supreme fuses 5amp slo-blo. I find double runs of Kimber 8tc 10ft lengths excellent.Two of the finest amplifiers to drive Acoustat 2+2 electrostatic speakers are the valve EAR 549 monoblocs & CAT JL2 signature mk2 stereo amp; I have both. Very few amps drive Acoustats properly;these amps do. A great speaker and highly underestimated.Must be set up carefully and properly.A credit to Mr Jim Strickland the designer.

I've got the Three panel model X with the servo tube amps, modded and upgraded(lots of Furutech parts)
I also like the sound of a passive pre amp, in my case, the LightSpeed Attenuator.

I have other friends who use tube pre amps and their sound is not as clear and defined as my sound is.
I thought it was the upgrades, but perhaps it's the LSA.

Enjoy your 2+2's.

I've had stacked 57's, a pair of 63 on Arcici stands, Martin logan CLS 11Z(2 pair) and way back the medallion Acoustat3 with a Conrad Johnson MV75-A amp and CJ Premier two pre.

They all have something special about them, but what I have now is the best sound that I can remember with any of my stats.

Of course these are powered by the servo amps, so that takes a lot of the guesswork out of finding the right matching amp.
I don't think using the same amp to audtion the Quads and the Acoustats is going to give you a definitive answer.
One speaker will be handicapped.
Borrow a few different power amps if you want to get the full measure of either speaker.
