Review: Acoustat Trans Nova Twin 200 Amplifier


Category: Amplifiers

Lived in S. Florida during the time Acoustat was in business there and knew many of the principals there. Talk about a bunch of fanatics dedicated to high end audio,would be a gross understatement. The folks at Acoustat lived,breathed,slept,and played as hard as anyone in audio.It was truly their whole reason for being. The products they brought out were astounding and have truly stood the test of time.

One such product was their first power amp, the Acoustat Trans Nova Twin 200,also known as the TNT 200. For several years they auditioned practicaly every amp out there. Knowing full well that the amp would have to be exceptional in order to drive properly their range of electrostatic speakers,with their widely varying ohm load. Frustration after frustration ensued with each amp they auditioned. Those that could drive them just did not have the sonic signature the speakers needed. Consequently those that did have the signature they were seeking just did not have the current to do the job.

Face with this dillema,the only recourse was to build their own amp. Armed with the things learned in the auditioning the other amps,they now had a focus on what to do. The Acoustat TNT 200 was to be a fully MOSFET amplifier from input stage to output stage. Probably the first to use this type of topolgy. No one knew their speakers better than they did,so the amp was built knowing it drive the Acoustat line of speakers.

The first review of this Amp came from "The Sensible Sound" #17 Spring 83 issue. In the comparison it was matched against the Van Alstine Transcendance 400.

While I will not to into excessive detail here,the review on the Acoustat was most favorable. The TNT 200 has a more discernable sound than the Transcedance. Percussion has a seductive silkiness that is very pleasing.The mid range the amp excels with great detailing,with a very wide sound stage.While the top end frequencies,have a clarity and depth not often found.

I have used many different amplifiers with different Acoustat speakers. None of them for me really filled the promise. Finally located a TNT 200 and had a friend of mine who use to work for Acoustat rebuild the amp and add all of the updates.

Once you hear this amp driving a pair of Acoustats,you will then know why all other amps pale in comparison. This amp has the muscle,transparency,sonic signature,depth,and clarity that Acoustat Speakers need. And at prices in the secondary market are a true steal.

So if you have Acoustats or any electrostatic planar speaker here is your amp. The search is over. As far as conventional speakers go this amp will drive them with a verve that will astound you.

At the very least this amp will make you want to listen to every album or CD you own. A true glorious delight.

The Acoustat TNT 200 was not a Hafler design. It was designed by James Strickland and if memory serves me correct Frank Van Alstine had some input with the design.The TNT 200 was built in the Acoustat factory in Ft. Lauderdale,Fl. Thanks for the remarks - Much appreciated.
I haven't heard the Acoustat, but Jim Strickland eventually landed at Hafler and designed the 9300-9500 series Trans-Nova amps. I had an original 9500 for over 8 years. It is a very good amp. Not often available used, but a good value when available.

Hi Ferrari,

Thanks, poor memory I guess.. I believe Van Alstine did the phono sectin design for several of the Acoustat preamps, but as far as I know had no input into the amps.
I have a pair of Acoustat X's with the servo charged amps built into each speaker. While they are old and yes, they don't do so good with the bass, I use them in my screening room with my High Definition Projector. i use only two channel.

They are quite the curiosity and they work really well. For further information on Acoustat, try doing a web search on just the word, 'Acoustat'.
