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.

The MP-501 received all praise from our users all over the world. Today, we are glad to announce the MP-501 V2, the second edition of the MP-501. Two important upgrades have been implemented in the MP-501 V2. First, all PCB boards are upgraded to the highest quality, full gold plated boards. Second, the signal coupling capacitors are upgraded to the leading-edge Mundorf MCAP silver and oil series. These upgrades provide better smoothness, clarity and transparency to the music.

The MP-501 is a brand new design equipped with the most powerful KT120 pentode power tubes that can produce 55W per channel into 8Ω and 4Ω. In order to achieve high power output without sacrificing sound quality, two KT120 are configured in single ended parallel mode instead of push-pull. Dual power transformers with independent DC filtering circuits provide the best channel isolation performance. Huge total filtering capacitance provides low noise floor and reserved energy. Oversized output transformers can produce much deeper bass. Our zero global negative feedback design provides the most natural feeling and huge lifelike soundstage.

Features:

• Auto biasing design that eliminates manual adjustment.
• Class A single ended parallel; Zero negative feedback.
• Built with high grade genuine components.
  (US Military Vishay Dale resistors. RIFA 450, Rubycon, Philips BC, Panasonic and Nichicon capacitors.)
• 24K gold plated input and output terminals.
• Transformers are specially made with oxygen free copper wire and Japanese Z11/M6 silicon core.
• 2 oz. thick copper PCB.
• Proven by many audiophiles. Excellent sound quality guaranteed.
