Audiophony CX-400 : Phils21's user review
This amplifier after the bench trial of the story of sonomagazine February issue # 310 AudioPhony the CX1200 series seems fair to delivering performance and power are not exactly defined but the signal to noise ratio is very dynamic. I rub several vendor that is no problem about the transistors and all of the circuit.
