Unrivalled audio.

Audio redefined.

As the CD slides into the player and the first notes ring out through your speakers, the first pluck of the string and soft vocal should hit your ears with pure, undiluted pleasure

If it doesn’t, we have the answer. The DP-777 Digital Processor.

Unrivalled HD audio.

AMR believe no stone should be left unturned in delivering high-definition audio.

That’s why we loaded the DP-777 with a Gemini Digital Engine, which includes not one but two distinct chipsets:

  • The High-Definition 32-Bit DAC – to produce the ultimate audio from HD recordings
  • The Classic Multibit 16-Bit DAC – to harness the best audio from CDs

These give the DP-777 the edge over the competition with sound that’s clean, crisp and without equal.

The tech spec.

The DP-777 also includes the following AMR exclusive components:

  • Zero Jitter Mode – to eliminate distortion and jitter from your speakers
  • Global Master Timing – which picks up 28 million frequencies and eliminates jitter at its source
This is HD audio at the peak of its powers.

Unleash real potential.

If you’re looking for pitch-perfect instrumentals and clear, natural vocals, then the DP-777 will strip away jitter and noise to unleash the real potential of your CD collection.

It just sounds real and life-like.

Enjoy for hours on end.

Savvy emotion AMR DP-777 DAC signature edition

Listening to the predecessors, playing the sound is like a scorpion. When you feel that you have already known a little bit, you may be able to touch your feet. For a glimpse of it, only the ‘audio elephant’ is full of appearance. How much fun, this time, I took the initiative to ask the scare pigs to try AMR, a word of mouth, a good voice, “I want to try the microphone, AMR is wrong” Oh! Happy to die, I wrote my heart 3… The CD and DAC first.
