T100MPA Mono Power Amplifier
“The T100MPAs, and their sister stereo amplifier the T100SPA, use the same patented technology inside. We hear familiar recordings shorn of all but the last smidgin of sonic pollution and now revealed in all their pristine dynamic and tonal glory. The experience cannot be un-heard. From that point on, all other amplification just sounds plain wrong; we cannot stop our attention zooming in on intermodulation and hash that we now know to be artefacts caused by EMI and microphony. Watch the industry play catch-up.”

Performance
Born from the acclaimed T100SPA stereo power amplifier, the T100MPA monoblocks carry its circuit topology forward—and then go considerably further. Drawing on more than two years of focused research into vibration control and EMI/RFI management, the T100MPA delivers a sense of control, scale, and musical authority that feels effortless, inevitable, and deeply engaging.
Technology
The T100 series of power amplifiers rejects convention in pursuit of a singular goal: eliminating the noise that inevitably arises when a delicate musical signal is transformed into the power required to control demanding loudspeakers.
Specifications
Rated at 130 watts into 8 ohms, the T-Series Mono Power Amplifier delivers power with complete composure, maintaining absolute control even into the most demanding loudspeaker loads. Driven by our patented QPower™ technology, and capable of supplying over 10 amps of continuous current with astonishing signal-to-noise ratio performance, the T100MPA imposes nothing on the music—adding no weight, subtracting no nuance, only revealing what is already there.
Technology
Power amplifiers are uniquely vulnerable to microphonic noise. When left unchecked, it strips music of its urgency, blurs timing, and erodes emotional impact. From the outset, the T100MPA was designed to eliminate these losses—not by force, but by removing the conditions that allow them to arise. Central to the design is QPower™, our advanced noise-absorption architecture deployed on the direct current (d.c.) power supply to the audio boards.
Under high musical demand, traditional amplifiers generate significant vibrational and electromagnetic interference (EMI/RFI) within the power supply. This energy propagates—initially back through the mains connection and subsequently into the signal pathway—thereby subtly degrading the audio quality. The consequence, though subtle, is profound: a diminution of dynamic vitality and the introduction of microphonic distortion via intermodulation. The T100MPA addresses this at the source. By extending the ground-matrix architecture of the T100SPA and doubling its vibration and EMI/RFI absorption across the ground plane, unwanted energy is given a direct, efficient path to be safely dissipated—never allowed to reach the audio circuitry where it can do harm.
Seven proprietary modules form the T100MPA’s QPower™ configuration, lowering the noise floor to a level where phase information—so critical to realism, space, and musical presence—is preserved with extraordinary fidelity. What remains is not an exaggerated sound, but one that feels unforced, stable, and profoundly convincing.
Every aspect of the enclosure is crafted to complement the musical experience. The chassis is precisely machined from high-grade aluminium using Quiescent’s proprietary techniques to reduce vibration and electrical noise. A high-quality non-metallic top plate is employed to avoid the negative effects generally linked with a Faraday cage, thus protecting the most delicate circuitry beneath. No pre-fabricated casework is used; each component is meticulously designed and manufactured to meet our stringent standards.
With vibration and EMI/RFI addressed so comprehensively, the full potential of the amplifier’s core architecture is revealed. High bandwidth and current feedback provide speed, precision, and transparency, with vanishingly low phase error. Imaging locks into place, the soundstage expands naturally, and music unfolds with a sense of presence that draws the listener in and refuses to let go.
The T100MPA does not simply advance amplifier design. It breaks with convention to establish a new reference for how power, control, and musical truth can coexist.
