Normally, what you see is what you expect: a car has four wheels; a bicycle has two and an amplifier has two channels – or one if you are really lucky. But just because that’s the way things are it doesn’t mean it’s the way they have to be…

Buy a conventional stereo amp and you’ll lose money on it when you upgrade. But if you invested in the CH Precision A1.5 stereo amp, its sophisticated software control of input and output topology will allow you to reconfigure the amp you already have for active/passive bi-amping, as a high-current or high-power bridged mono-bloc (and more) at the touch of a button. It can adapt to different speakers and different rooms, grow with your system and match your ambitions. It will do big and it will do small. It is as impressively versatile as it is musically impressive. It really is four amps in one.
