The CDA2 can serve centrepiece of a comprehensive, yet relatively simple audio system. Consider - one box houses a very competent CD player, a high quality pre amp, and a USB DAC capable of resolution up to 384 kHz/DSD256. That is a lot of functionality in a single box, and the CDA2 performs all three tasks with aplomb. The CDA2 has a full complement of inputs and outputs. There is a 3.5 mm analog input for cellphones and tablets. The CDA2 has both XLR and RCA preamp outputs. It even has a headphone output.

The output stage has three MOSFET devices per channel and can achieve peak current output of over 15 amps. the P2 can drive virtually anything. It's a beast, but an extraordinarily musical one, capable of delivering wonderful tonal accuracy and nuance, as well as incredible control and dynamics. The P2 is a great choice for larger rooms and speakers.

ATC is such a prolific speaker making company that their electronic components are often overlooked and underestimated. It would be unfortunate to overlook the P1, because it is a highly proficient amplifier. Rated at 150 WPC of class AB power, this true dual mono design amplifier is rated as a Class A component by Stereophile. For a relatively low cost, the P1 renders music with character, authority, and insight, and is capable of driving a very wide variety of speaker loads. Additionally, it behaves well with pretty much any preamp you might care to pair it with.
