Line Characteristics

FM Original Parameter Core Circuit

The left and right channels are completely independent with no electrical connection

With a layout that surpasses the original design, the entire unit is extremely stable and operates completely noise-free.

Ingredients and Preparation
16 newly manufactured test pairs of <1% gold-sealed tubes 2N3440/5416 produced in recent years

The test pairing involves groups of 20 units each. For the Japanese-origin brand's brand-new ON transistor MJL4281, selections must be made from over a thousand units.

Each large tube is connected in parallel with a decoupling capacitor and an electrolytic decoupling capacitor.

800W high-quality Nippon Steel core transformer with independent windings for left and right audio channels

Quality Assurance and After-Sales Service

To ensure quality, each complete unit undergoes comprehensive AP testing to meet all design specifications.

The tests include: bandwidth, noise (signal-to-noise ratio), dynamic range, distortion, intermodulation distortion, channel separation, and gain.

The entire device underwent a 72-hour stress test; the power amplifier was tested under full load (8 ohms) for 1 hour, followed by over 1 hour of audio playback testing.

The entire unit comes with a 1-year warranty, and repairs can be performed at the original cost for life.

The entire device supports a 15-day trial period. You need to cover the round-trip shipping costs.

The FM711 Master Edition delivers exceptional AP test performance, with each channel capable of handling a 6-ohm load at 700 W.
