Dual-Mono Amplifier

Feel the thrill.

Just feel.

When you hear the first note of your favourite tunes with natural purity, it’s a feeling you’ll never forget.

It’s the feeling of the hairs on the back of your neck standing up.

The feeling that your favourite bands are right there with you.

This is the AMR AM-77.

R-amp it up!

An amp’s job is simple – to enhance your enjoyment of music.

However, many don’t, making your audio sound unnatural and bleached. Not anymore.

The AM-77 drives even the most difficult of loudspeakers and addresses poor sound by injecting:

  • Speed
  • Rhythm
  • Life

via a fusion of valve and solid-state tech, into every vocal and instrument, allowing you to enjoy ‘live’ music every time.

Awe inspiring sound.

Boasting a spacious soundstage, the AM-77 delivers a truly inspiring sound that’ll have the hairs on the back of your neck standing up every single time you hit play.

And that is no bad thing.
