Information on Acoustat 2plus2 speaker upgrades.

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.

Thanks so much for taking the time to answer my question. I was thinking on sending the electronics to a man in Ohio and have the upgrades done. He said I could have alot of upgrades for around 1000.00. Copper caps, new ac sockets, new wire, remove fuses new speaker post. Jim

Check out this web site. The discussions are by the designer of Acoustat speakers.

I replaced the speaker post with Cardas CPBP CRS
and the AC inlet with a filtered IEC inlet.

Have a look at mracoustat 1+1 s in the members systems in the community section. Is that the kind of improvement you are looking for ?

The same gentleman who did this job is actually rebuilding my Acoustat 3s into 2+2 s and I saw the new woodframe this last weekend. Astounding ! Layers of thicker plywood in replacement of original press wood. Much heavier for optimum rigidity. A shame to cover them with the sox. As per previous posts, the electronics can be rehauled and replaced with better parts, wire changed for silver or better quality, the membranes soaked and cleaned to renew their flexibility. Cell heads wiring stripped and soldiered for better dynamics. Heard the results of the process on his own pair of 6's. Oooooooohhhhhh my ......
