MP-501 V5 is our flagship integrated tube amplifier. It is a big upgrade from the legendary MP-301 MK3 in terms of sonic details, dynamic and power. If you have low efficiency power hungry speakers, MP-501 is your solution. MP-501 can provide good bass response, big soundstage and very fine sonic details to the audience. Its sound signature combines both solid state and traditional tube advantages. It is a comprehensive amplifier that not only can play very sweet and smooth female vocal, but also can handle high dynamic range symphony unbelievably well.
 
MP-501 employs powerful Tung-Sol KT120/KT150 pentode power tubes and produces 55W per channel into both 8Ω and 4Ω. In order to achieve relatively high output power without sacrificing sound quality, power tubes are configured in single ended parallel mode instead of push-pull. Dual power transformers with independent DC filtering circuits provide the best channel isolation and strong power supply performance. Zero global negative feedback circuit design delivers the most natural and musical sounding.
Features:
Circuit Configuration
Single-ended Class A, zero negative feedback, automatic bias voltage design.
Power Supply
Imported high-quality iron core ring transformers are used, for left and right channels separately. The left and right channels are powered independently. High-quality Hi-fi power filter capacitors, combined with left and right independent filter inductors, provide pure and abundant power supply for tube amplifier circuit.
Output Transformer
It is made from imported Z11 EI iron core, oxygen-free copper enameled wire wound in multiple layers.
Vacuum Tubes
The preamplifier and booster tubes use 6J8P (6SJ7) tubes dedicated for audio amplification. KT120 or KT150 are used as power amplifiers tubes. It outputs 55W per channel. KT series power tubes are designed with large output power, high energy efficiency, sound balance, moisturized sound, and excellent transient response.

PCB Circuit Board
Adopt advanced immersion gold process double-sided FR4 glass fiber board to ensure excellent current transmission performance and oxidation resistance.
Premium Components
Use high-quality US military grade resistors, German coupling capacitors, imported Hi-fi filter capacitors, Japanese motor remote volume potentiometers.
Loudspeaker Output
Support 4Ω-8Ω loudspeakers, KT120 / KT150 power tube (55W per channel). Gold-plated output terminal supports banana plug, Y plug, and direct twisted wire.
Exterior Design
The shell is made of high-strength thick steel plate, and the panel and knob are made of solid aluminum alloy CNC. The concise panel allows you to learn how to use it in just a few minutes, without having to read manual in advance. 
Sound Characteristics
The sound is vivid and natural, smooth and delicate. Wide sound field and strong three-dimensional sense. Strong low-frequency dynamics, medium-frequency moisturized sound, high-frequency delicate and elegant sound. It performs well in vocals, strings, and symphonies. It is a flagship integrated amplifier with powerful performance and driving force.
Remote Control
It support IR remote to control volume.
Frequency Response & THD
