Information on Acoustat 2plus2 speaker upgrades.


I have Acoustat 2plus2 speakers and have really enjoyed them. Ive has Sound Lab M1 and A3s, Martin Logan CLSs, Quest, Magnepan TYmpanis and alot of other planar and electrostatic speakers. Presently I have the 2plus2s and Yankee planars. My listening room is 20x30x12 and I have a wonderful wife and son who doesnt mind my speaker systems. I want to know if anybody does upgrade work on the 2plus2s. Also does anybody know how to make them look better than they do. Such as bases or wood rails,etc. Im using Threshold SA-2 monoblocks, the FET-9 preamp. I have a Roksan Radius 5 table and a Esoteric transport with a Meridian DAC.

Turning off the lights is probably the only thing you can do.

I'd start by upgrading the capacitors in the signal path. The electrolytics they used from the factory were really bad. Follow that with some wiring and connector upgrades and you have a great sounding speaker! Shoot me a line if you'd like more details or advice on any DIY upgrades... or I can do the mods for you if you wish.

I have a set of Acoustat 2+2's and obtained beneficial results from replacing the three electrolytics in their input section with North Creek Zen capacitors. The huge Zens barely fit and are now, sadly, discontinued, but you could probably find similar replacements. I've read that the blue and red medallion upgrades -- assuming you can even round up the parts these days -- don't yield noticeable results.

Amplifier-wise, I've run mine on a McIntosh MC7300, an Acoustat TNT-200 (modded), and a Hafler 9505, but what bested them all in my setup was a PS Audio HCA-2. These class D amps are selling used on Audiogon for less than $600 these days.. a steal, and imho, a fine match for Acoustat speakers. Research the HCA-2's SDAT output section and its 'high damping factor load invariant power' to get more insight into why this is so.
