Class D Chip

Tri-Art Audio amplifiers utilize Class D amplification. Until very recently, Class D amplifiers in audio had been used mostly in professional audio designs where the advantages of their efficiency, their low weight, and their low operating temperatures are of real benefit to touring concerts and musical productions. The conventional wisdom has been that Class D amplifiers did not sound good enough to be considered for high fidelity applications – that they are extremely susceptible to external and internal noises, such as microphonics.
Our goal was to create an environment as close to vibration-free as possible in order to let the amplifier circuit work to its full potential: to be able to hear the chip, possibly for the first time, without the distortion of microphonics.

Capacitor Banks

Class D amplifiers are particularly sensitive to any anomalies in their supply voltage. Although we are using an exceptionally good power supply, we decided to go the extra mile and incorporate a capacitor bank – ensuring sufficient current will be available to the chip to deal with high transient demand conditions.
Multiple smaller capacitors in a bank can be preferable to a single large capacitor, mostly for reasons of speed, but these must be very carefully designed to avoid the generation of eddy currents.
By strategically deploying small amounts of resistance to balance transient draw, we have created conditions antithetical to the formation of eddy currents.

Fuses

Fuses are an extremely important element for the power supply. They are the most significant choke point with the greatest potential for negatively affecting component performance.

Tri-Art Audio uses AMR Gold Fuses exclusively in our amplifiers and Linear Power Supply in order to avoid these issues. Unlike the generic fuses, the AMR fuse is a reference replacement fuse made with high grade silver alloy wire in an anti-resonant ceramic body, with special gold-plated copper, and non-magnetic end caps.
AMR fuses have excellent conductivity, extremely low levels of microphony, and end caps that will not degrade, providing reliable contact for decades.

Naked Components

All electronic components on our circuit boards have had their outer skin (plastic shrink identifying wrapping) removed.

And for good reason: we discovered during our listening tests that stripping away plastic wrapping removes the sonic characteristics plastic brings to the electronic component.

We remove as much associated materials as possible that have negative sonic signatures.
