The MP-3 preamplifier is based on the concepts pioneered by our MP-1 preamp in a single chassis. Recently updated to Mk 3.3, the MP-3 is a fully differential all-tube preamplifier with a direct-coupled high current output capable of driving low-impedance balanced-lines. The MP-3 easily drives interconnects over 200 feet long! The MP-3 extracts more ambient information with greater image specificity, bass definition and dynamic range than any single-ended preamplifier, owing to its patented direct-coupled output. Furthermore, it perfectly complements the balanced design of our amplifiers or any balanced power amplifier. The patented innovations, developed specifically for this preamplifier, make the MP-3 one of the best preamps made today.

Balanced line technology has been in use in the recording and broadcast industry for decades, and is why the high fidelity era began in the early 1950s, long before exotic interconnects existed. Balanced lines sound better than single-ended cables; are dramatically more resistant to RF, hum, cable artifact and cable length. The low impedance balanced line system is a means of preventing interconnect cables from having a sonic signature. The MP-3 supports this system, so you can run long cables with no need for exotic interconnects and still get exemplery performance.

In addition to its remarkable line section, the MP-3 works well with low-output moving coil cartridges and uses a minimum of connections in the front panel wiring and controls. A low number of gain stages (only three from phono input to line level output) insures low distortion, wide bandwidth and superb dynamic range. The result is a truly musical package of exceptional value.
