AMR AM-77.1

Hybride Dual Mono Amplifier


Solid-state amplification has taken the listener to ever more power and ever higher specification levels. This has led to many a solid-state amplifier sounding increasingly unnatural and bleached. The AM-77 Dual Mono Amplifier seeks to redress this: through a fusion of valve and solid-state, it is the only high-powered amplifier in the world that: 

"Sounds like an exceptional Single-Ended Triode(SET) valve amplifier." 

With a pure 180W per channel, the AM-77 uncannily boasts pure power with the ability to drive even the most difficult of loudspeakers with speed, rhythm and most important of all, life; each voice, instrument and performance sounding just like the real thing. At the heart is a no compromise combination of zero negative feedback, pure Class A valve stages in the pre-amplification section coupled in the power amplification section, with bipolar output devices in AMR’s proprietary “Class X: Jikoda” circuit. The AM-77 is one of the very few amplifiers able to move the listener with a stirring and touching musical performance reminiscent of an exceptional SET valve amplifier does.
