BRZHIFI Reprint Swiss Famous Machine FM711MK2 Pure Rear Series

The FM711MK2 direct carving is a landmark product for us!

Over the past few years, we have successively etched various renowned machine circuits, continuously absorbing the essence of product designs from different brand manufacturers. It should be said that each major brand has its own unique understanding of audio circuits and embodies it in their products. The same applies to FM’s amplifier circuits, where the entire series of output circuits employs extremely easily precision-matched like-polarity power transistors. The most critical input loop places stringent requirements on differential circuit components, which is the reason its sound can achieve exceptionally low distortion and accurately reproduce the original tone. This is precisely why FM’s sound stands out among numerous brands and commands exorbitant prices. Audiophiles who have used our FM300A should deeply appreciate this. For this FM711 recreation, we approached the project with a more rigorous and reverent mindset, strictly adhering to the original machine’s design philosophy to complete this product

FM711 Technical Features:

The FM711-mkii features a larger-scale power supply with immense power, utilizing a high-current-capacity high-speed dual rectifier.

The new module is designed for input and achieves an impressive 100dB (!!!) common-mode rejection (such as noise and other interference, hum, must be canceled before the amplification stage). They enhanced the FM 711-mkii anti-interference. This common-mode rejection ratio reaches a level that does not exclude inexpensive op-amps, allowing independent fine-tuning of discrete circuits to ensure the final product is called FM Acoustics.

The common-mode rejection ratio test diagram is as follows

3: Deliver immense power to drive the most demanding loads, utilizing proprietary discrete circuits with specialized curve tracing analysis and hand-selected semiconductors, featuring superbly balanced discrete input stages. The sensor automatically identifies connection standards and effectively balances both balanced and unbalanced signal sources, including pseudo-balanced inputs.

4: The power amplifier and speaker protection system triggers output and automatically resets when the error disappears.

5: There is no signal compression, and no other negative effects on the audio signal are possible. All audio stages of the protection circuit are completely isolated.

6: Output drives any speaker load, even very low impedance or higher capacitive sensors, with a unique dynamic damping effect, delivering a perfect pulse response and no ringing.

7: The proprietary premium-grade circuit delivers unrivaled music, with award-winning circuit technology ensuring zero distortion in any form—whether dynamic or static—even at the lowest signal levels, surpassing other designs in scale.

8: FM acoustic isolation with new mechanical resonance elimination support, low-impedance power source delivers infinite rendering, and new high-reliability components contribute to further extended lifespan.

The newly finalized version has significantly improved testing metrics and listening experience. After AP testing, it strives to achieve a unique sound that audiophiles can purchase with confidence.

The reason why classic phones are classic is because they used special components made of customized materials in a specific era, perfectly integrating art and technology, which created the emergence of a generation of famous phones.
At the audio exhibition, many friends have increased their confidence in our company’s products after listening to them. At the suggestion of several experienced music enthusiasts, we made a customized version of the 711 amplifier. In order to produce this product with unique sound and materials, we have decided to use the best components from the entire company to make this machine.
One of the indispensable contributions is the overseas transistor supplier, who found a batch of brand new gold sealed diodes produced in 1981 in the market. It should be noted that the peak period of audio development also began in this era and gradually declined around 2000. In that era, many factories customized components from manufacturers in order to make their products sound unique, including many world-renowned audio factories in Switzerland, Germany, the United Kingdom, the United States, and others.
The frequency characteristics and parameters of this pair of tubes are very good, with extremely high voltage resistance, which perfectly conforms to the high voltage working mode of FM. After receiving the sample for testing, we went through three rounds of blind listening by several audiophiles with golden ears, and everyone gave high praise. Both the high, medium, and low frequencies of the sound are impeccable, reflecting an unprecedented sense of looseness and delicacy. The music, without any sense of oppression, hits the face and leaves a stunning impression as soon as it starts, completely forgetting the existence of the sound system. So we decided to use these tubes to make some different machines to give back to our friends who have always supported us.
