The interior of our amplifiers are packed with locally sourced, unbleached, sheep’s wool due to its ability to reduce sound transfer and vibrations, insulate, and natural heat resistance.
Wool fibres are particularly effective at dampening airborne vibrations and preventing them from affecting the performance of our amplifier chip.
The temperature stability of the system (class D) and insulating properties of the wool have the benefit of eliminating heat sinks. Wool also eliminates the need for fans which are both mechanically and electrically noisy. Applies to P-Series, B-Series & Block.

We developed our locally manufactured concrete brick using a blend of cement and plastic fibres to re-enforce its strength, make it lighter in weight, and more porous.
Concrete absorbs sound frequencies and resonates at a narrow high-frequency, and its porosity allows for sound absorption. Applies to Block.

We have selected bamboo to construct many of the structural parts of our systems rather than the industry standard of metal or plastic.
In addition to its natural aesthetics, it has a vital function: A constrained layer plywood variant is employed for its performance abilities. It is very stiff for excellent rigidity with the ability to dampen vibration. It is non-magnetic, providing a quieter electrical environment for our amplifier circuitry.
An eco-friendly resource, some variants of bamboo are capable of growing up to a meter (39 inches) per 24 hours period! Applies to P-Series, B-Series & Block.

The power supply is by far the noisiest section electrically in all amplifier designs.
The single most important fact about our 24V DC Linear Power Supply is that it is housed in its own enclosure, physically separated from other units.
Instead of the less costly and more commonly used Switching Power Supply, we use a Linear Power Supply which are five orders of magnitude (10 000 times) quieter than the cheaper option, allowing our amplifier chips to operate to their full potential. Applies to B-Series & Block.

Another feature to keep our products as vibration free as possible is to physically isolate our chassis from the surface it is sitting on.
We achieve this by resting the chassis on a trio of re-purposed automotive ball bearings, themselves sitting in an indentation at the top of shallow metal cones which are then set into a multi-layer, laminated, bamboo puck. Applies to P-Series, B-Series & Block.

Our Turntable Bearings are composed of a chorus of materials, all working together, to achieve a high level of sonic unity. Applies to P-Series & B-Series.

• Our Pebbles bearing features a stainless steel shaft with inlaid copper into the spindle.

• The sub-platter is machined aluminum.

• At the base is a machined brass outer sleeve tube with a half-inch copper plinth that seats the main ball bearing, lubricated with grease.

• The collars that bolt the bearing to the base are machined aluminum as well.

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. Applies to P-Series, B-Series & Block.

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. Applies to B-Series & Block.

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.
Applies to B-Series & Block.
