ATC SIA 2-150 stereo integrated amplifier

ATC SIA 2-150 stereo 150W per channel integrated amplifier.

What we Say:


The ATC SIA 2-150 is the larger of the two integrated amps in the ATC range. It features 5 line level inputs and has a built in headphone amplifier. The standard of construction is very high, the first thing you notice is the weight. It features two separate transformers, one for the pre-amp section and another for the power. The ATC SIA 2-150 is a Mosfet based design capable of delivering 150W per channel into 8 Ohms.  It will drive most loudspeaker with ease.


See attached technical specification.

Upgrade path:

The next step up in the ATC range would be to look at the CDA2 with a P1 or P2 power amplifier.
