Our take on the NuPrime AMG One Mono Amplifier

The NuPrime AMG One is a compact mono power amplifier rated at 170W into 8 ohms and 220W into 4 ohms, with peak output of 210W and 260W. NuPrime describes it as a scaled-down version of its Evolution Two, so it borrows the same class-D design approach in a much smaller 11.2 x 9.25 x 2.2 inch, 11 lb chassis. A single unit drives one channel, so a stereo setup needs two. It suits listeners building a separates system who want high power per channel without large, hot amplifiers, and it competes with other compact class-D monoblocks on power and size rather than on features.

Pros
  • High power for its size: 170W into 8 ohms, 220W into 4 ohms
  • Peak output of 210W and 260W for short transients
  • Wide 10Hz to 50kHz frequency response
  • Very low standby draw of 0.4W
  • Small, light chassis at 11 lb
  • Balanced 47k ohm input impedance suits a wide range of preamps
Cons
  • Mono design: two units needed for stereo
  • No built-in preamp, DAC or streaming
  • Gain of x21 and 1.7V sensitivity demand a capable preamp
  • Class-D amps can be sensitive to speaker load matching
  • Few front-panel controls or features

Questions and answers

Do I need two AMG One units for stereo?
Yes. Each AMG One is a mono amplifier that drives one speaker, so a stereo system needs two units.
Can it drive 4-ohm speakers?
Yes. It is rated at 220W RMS into 4 ohms and 260W peak, up from 170W and 210W into 8 ohms.
How does it compare with the Evolution Two?
NuPrime calls the AMG One a scaled-down Evolution Two. It uses the same design direction in a much smaller, lighter chassis with lower power output.
What preamp does it need?
It has no volume control or inputs beyond line level, so it needs a preamp. Its 1.7V sensitivity and x21 gain mean a preamp with normal output and a gain stage will drive it to full power.
What is in the box?
The amplifier itself and its power cord. Speaker cables and a preamp are not included.
Does it run hot or use much power at idle?
Idle draw is about 8W and standby about 0.4W, so it stays cool and efficient compared with large class-AB designs.
Where is the NuPrime AMG One Mono Amplifier cheapest?
At NuPrime Audio, for $1,299.00, as of our latest check.
