AM-777 SE

Size isn’t everything.

Music is emotion.

From the first note to the last, music should move you. If it doesn’t, then get ready for the AM-777 to rock your world.

Stirring sounds.

It’s predecessor, the AM-77, was a real game-changer for amplifiers, but the AM-777 goes one step further by producing music that stirs your emotions.

Vocals are elevated and instruments are separated to produce first class musicality.

And the AM-777 achieves this by injecting:

  • speed
  • rhythm
  • life

into every vocal and instrument, allowing you to enjoy music ‘live’ in your own home.

You got the look.

With it’s brushed aluminium chassis, the AM-777 doesn’t only sound high-quality, it looks it too, which means not only will your music sound good, it will also look good.

HiFi World December 2011, AM-777 Review

Well-known vinyl lover Tony Bolton of HiFi World penned a very complimentary review of the AM-777 Premier Class Pre-Main amplifier. The AM-777’s character was neatly summarised by his narrative…”it didn’t try to force the listener to take notice, but laid the music out on display, then seemed to step back and let the tunes speaker for themselves.”
