Best amplifier for Acoustat 2+2 electrostats for holographic sound, or change speakers?


I seek your opinion on how to improve the holographic sound out of my current system, which has the Acoustat 2+2 full range electrostatic speakers, solid state Sound Spectrum Technologies (SST) Ampzilla 2000 SE monoblocks (300 wpc, high current), and 2 preamps - a solid state SST Thoebe 2 and a SAS Audio Labs Reference 11A tube hybrid (which I am using currently).  Sources are a Yamaha PX2 turntable with Hana Umami Blue cartridge, Eastern Minimax tube phono stage, a Musical Fidelity A5 CD player (as transport) thru an Audio Mirror Tubadour IV SE DAC and an Eversolo DP6 server.  I also have a Moscade Saturn active subwoofer.  Room treatments include dispersion panels behind the Acoustats, bass traps at the corners and some DIY absorption panels plus miscellaneous isolators on the equipment.  Cables are a mixed bag  with nothing very expensive. The listening room (my study) is 22' x 13' x 8'. 

I listen to jazz and vintage rock.

I can't afford to remake my system and like the sound of the Acoustats but want the sound field to extend more beyond the panels and the imagery to be better defined.

I have read that a push-pull tube amp could result in a more holographic sound.  What should I look for in terms of tube amp design and power output?  Can you recommend any specific amps? 

The alternative is to change speakers, one big issue being selling the Acoustats, which because of the 8' height are a challenge to ship.  The other is selecting from the hundreds of speaker choices. 

My budget is limited - I don't want to spend more than $1K over what I'd realize in selling either the amps or the speakers and I'd buy pre-owned.  I live in the Atlanta area.

Appreciate your suggestions.  Thanks!

Having owned Acoustat model 3M's, I can tell you that they are limited to the imaging that you describe, it is only once you change speakers that imaging specificity and IME, a host of other benefits, can be had. YMMV.

My first set of high end speakers were Acoustat 2 + 2… 1979? They were awesome but I instantly realized that a much better amp was required if I was going to keep them. So I bought a high current amp ($5K 19K today)… but after that purchase I couldn’t afford the speakers. I never got back to buying them.

 

With trade in and only $1K, that just sounds like a great way to trade and end up unhappy. Now if you can add $5K to $10K to your trade in, I’d start looking. But I am risk adverse.

Your amplifiers are not destroying the spatial information you seek. I sold your 2+2 and many other stats. You don’t mention which wall you have them on and where the absorbers are… Typically audiophiles overtreat the room… w absorbers…typically also messing up frequently response by not using a broad band panel aka DEEP… diffusion on sides might help…

I agree 2+2 value plus $1K isn’t going to help much… and you will give up the magic midrange…

Just my $1.50
