Welcome to the Tru Technology area...

All of the products are hand-built in California. All amplifiers go through 110% quality control. The reason Tru states this factual 110% is that the products are hand-built one at a time and tested one at a time. Then, an additional 10% are re-tested at random.

Every one of the amps has been hand-built in one way or another. They all have their own identity. Not to be confused with build quality, performance, or mass production.

Steel Series

The Steel Series is where Audiophile Begins. These amps are designed with both the audiophile and installer in mind, with all power and signal terminals located at one end and the compact outer casing, with internal fan cooled heatsink so that the amp can be mounted in any location ( e.g. under the car seat ).
