Kharma - Matrix MP 150 Power Amplifier

The Matrix MP150 amplifier is a proprietary switching amplifier It uses a unique pulse control scheme that takes feedback only from the speaker terminals. No feedback loop from the switching output is used. The result is extremely low output impedance over the entire bandwidth. Damping factor is >400 up to 2kHz and >100 at 20kHz. The frequency response is DC-50kHz (+0,-3dB) and is completely independent of the load impedance. THD and IMD are very low (<0.02%) and completely independent of frequency, like a good zero-feedback amplifier.

"When it comes to tonal naturalness, ambient recovery, frequency balance, continuousness, transparency, depth, and sheer musicality, it is, for these ears, the only Class D I know of that I would choose to live with. It may not have quite the weight and texture, bloom, or high frequency extension of a really fine linear design, but it comes mighty close and is among the most beautiful sounding amplifiers I know regardless of type." Wayne Garcia, TAS, Issue 166



"Of all the ClassD/T amps in this survey that I have heard or reviewed, the MP150 is the sole one I could recommend without serious reservations for a high-end system. What it is is a very good solid state amplifier that gives you a taste of what a great solid state amplifier is capable of. If this quality of Class D amplification is the way of the future, then the future may be rosier than certain other amps in this survey might lead one to think." Jonathan Valin, TAS, Issue 166.

Tech Data

The amplifier operates without an oscillator which removes all problems associated with oscillator jitter. This translates into very good SNR > 110dB. Construction is entirely using discrete transistors and FETs. Input impedance: 220K!

"The Kharma MP150 offered at $6800/pair is a freak occurrence, a rare marketplace anomaly. This is a case of extreme value. Had they been packaged in a larger, fancier chassis, I have no doubt they would have no problem selling at $10,000 or more. I can't think of a competitive solid-state amp at anywhere near this price. The one that comes to mind is the darTZeel NHB-108 with its $18,000 MSRP. The MP150 is better." - Positive Feedback Issue 25
 

Einstein The Light in the Dark (Stereo amplifier) When mated with our EINSTEIN linestage ‘The Tube’, bass runs are reproduced with unheard-of speed that reveals sonic vistas previously only hinted at. This power amp is a must hear, way better than it has any right to sound for the money.

Boulder 850 Mono block Amplifier pair the highest standards of quality and reliability yet makes unequalled Boulder performance available to an entirely new audience. The all analog Boulder 850 avoids the sonic problems of switching amplifiers such as noise radiation, dynamic limiting, and IM distortion.

Boulder 810 Preamplifier Like its predecessors, the 810 Stereo Preamplifier features balanced, dual-mono, three-stage instrumentation-style circuitry. This eliminates any trace of noise, distortion, or impedance issues that may affect the delicate audio signal. Musical dynamics and detail emerge effortlessly from a black and silent background. Images are superbly defined and separated with a wealth of revealed low-level information.

Accustic Arts AMP IIt should be obvious by now that when it comes to treble performance; I regard
the Power 1 as the bee's knees particularly for a solid-state amplifier. In this regard, it is perhaps the best I've ever used. It illuminated treble details as no other amplifier I've heard,...
...Through the midrange, the Power 1 was as transparent as just about any amplifier I recollect ever hearing...
