Peachtree amp500

The Peachtree amp500 features a staggering 500 watts per channel into 8 ohms and drives speakers all the way down to 2.5 ohms - AND up to their full potential. It features a custom designed, class-A input stage and balanced and unbalanced inputs for compatibility with virtually any preamplifier or music source. The amp500 is housed in the same beautiful chassis and cabinetry as our award-winning nova series of amplifiers.

500 watts per channel has never looked or sounded this good!

  • Drive ANY speaker with ease and headroom to spare
  • Exceptionally low noise, even compared to MUCH less powerful amps
  • Balanced and unbalanced inputs with differential audio circuits
  • Custom designed class-A input stage
  • 127dB Signal to Noise Ratio
  • Aluminum front panel and chassis wrapped in a real wood cabinet finished in stunning Gloss Ebony Mocha or beautiful Piano Black

Imagine Your Music Emerging from a Black Background . . .

In the past, big powerful amplifiers have been great for dynamics and solid bass - but often at the expense of noise. In the amp500, Peachtree has achieved a high signal to noise ratio AND a very high power level - with both soft musical passages and huge dynamic crescendos seeming to emerge from a black background. It’s rare to find an amplifier this powerful and with a dynamic range capability of 123dB (127dB A-weighted). When a rim shot from a snare drum lifts you from your seat - that’s what this kind of power can do in your system. When the cannon from the 1812 Overture has the impact you’d expect at a live performance you realize that tons of power simply makes it sound more *real*. Yet at the same time you’ll get a nice delicate balance with a solo acoustic guitar or violin. High power and a high signal to noise ratio is what it’s all about.

Peachtree Audio's amp500 is a stand alone power amplifier based on the amplifier section of the nova500. It recreates the natural power and dynamics of live music with ease, and features a fully balanced topology that is extremely musical and faithful to the source material. The amp500 includes balanced and unbalanced inputs, a discrete class-A buffer stage and low-noise linear voltage regulators for input circuits. The amp500 effortlessly drives the wide range of high-performance speakers available today.
