M3 pure tube single-ended audiophile power amplifier

Product Description

1. M3 uses a 150W full-material power source, which is 50% more than the conventional power source to ensure sufficient energy
15W "no large loop feedback" super linear audio output cattle, nearly double the margin of the rated output power, in pursuit of better sound quality

2. The M3 audio transformer adopts the "cross compound process winding method", so that the leakage inductance of the output cow and the power inductance ratio are less than one thousandth, so it can show perfect sound quality in the audition at the same price.

3. Adopt the brand new 0.35 imported audio iron core, the magnetic flux is much higher than other models, the electrical state is stable, and the sound quality is more guaranteed.

4. M3 adopts Marantz M7 pre-amplifier and Marantz M8 post-amplifier, Siemens antique and amplification system, Western cinema amplification system, etc., as a reference for tuning.

5. Concise but not simple preferred circuit, M3 uses high current dual triode 6N1J as voltage amplifier, audio bile tube EL34 for single-ended power amplification, has the characteristics of large driving current, warm and rich tone, full and thick mid-bass, transparent and smooth treble .

The tube amplifier is divided into two modes of operation:
1. Single-ended: Just like a solo singer, the sound is pure and natural, the power is relatively small, suitable for family use, and the strength is not as good as push-pull.
2. Push-pull style: Like a chorus combination, it has a wide and powerful sound range, relatively large power, suitable for various places, and its charm is not as good as single-ended.
