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.

Accustic Arts PRE 1 MK 3 (BALANCED) Since the review the preamp has been updated to MK 3, the changes have updated the already excellent sound to a yet higher level. In our opinion this is now a faultless product and more than capable of standing any competitor in this price sector making it the one to listen to. In short you have innovative circuit designs using world class components and excellent German engineering, leading to a world class product within its sector. A best buy!

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.

Kharma Matrix amplifier pairThis 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
