Design Features

The input and driver stages of the C 272 are fed from a separate

low-noise, high voltage discrete component regulated power

supply, which effectively isolates them from the high current output

stage of the ampliﬁ er ensuring the lowest possible levels of noise

and distortion. Careful design incorporating sensible grounding

results in an ampliﬁ er with an exceptionally clean, noise free output

signal.

Other design features include the generous power supply with a

large toroidal transformer (less mechanical hum and stray magnetic

ﬁ eld) and over-speciﬁ ed robust output devices further lead

to low noise and low distortion. The C 272 exhibits extraordinarily

low levels of distortion at all power levels and under almost any

operating condition. Unlike most ampliﬁ ers, distortion does not

increase at the frequency extremes or even when presented with

low impedance loads. What little distortion there is remains the

same at 8 ohms or 4 ohms!
