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!
