And with all it's customised components, including custom precision Caddock resistors and tailor-made filter capacitors, it is one of a kind inside and out. There is only a single gain stage in the amp, so the signal path is very direct - something unknown in amps of this class.
It is class A, all-triode, and fully differential, with our patented direct-coupled output circuit and patented automatic bias control.

The MA-3 has all of the features as our other models, plus a few not seen in any other amplifier ever produced. It's high-power amplifier that is fast and truly musical! No transformer-coupled amplifier can produce 200, yet alone 400 watts and get it right at every audio frequency yet the MA-3 makes 500 watts easily, without electronic artifacts. Since we are not limited by issues that plague conventional amplifier designs, the MA-3 retains a wide bandwidth and low distortion simultaneouly. There is clearly a need for such an amplifier that can make serious power while being completely transparent and musical fortunately our OTL technology is well-suited to the task. The end result is arguably the the best amplifier in the world!
The goal: to build the largest OTL amplifier the world has ever seen, while at the same time retaining the qualities our amps have made famous. It was 7 years in design, with 15 different chassis and 12 different circuit concept explorations. The MA-3 is the culmination of a massive project we began in 1998 at the behest of one of our customers.
