ATC P1 stereo 150WPC power amplifier.

ATC P1 stereo 150W per channel power amplifier.


What we Say:


The ATC P1 is one of two power-amps in the ATC range. The ATC P1 is a Mosfet based design capable of delivering 150W per channel into 8 Ohms and is dual mono construction throughout. Both balanced and single ended inputs are available.


Moving from an Integrated amplifier to a separate Pre and Power amplifier give big performance advantages. The delicate incoming signal no longer has to live in the same space as the large power supply. The quieter environment preserves the integrity of the incoming signal.

Upgrade path:

The next model up from the ATC P1 is the P2. All ATC products are hand made in their facility in Stroud.

  •  Hand built in the UK and supported by a 6 year warranty.

“…if you want to hear the important musical detail presented in a coherent, clear-cut fashion this pairing has remarkably little competition in the two box arena. There are a few integrated amps which give them a run for their money in one respect or another but nothing comes to mind which seems like a better overall package.”
