A5CR Preamplifier
The
A5CR preamp is technically the equal of any at any price,
except that its overload margin and peak output capacity far exceeds
anything else available excepting our own kW preamp. The A5CR's
dual mono double choke-regulated system ensures virtually perfect
isolation from mains interference. Its distortion is vanishingly low and
its noise ratio is excellent. The A5CR may have a modest price
but its performance is right up there with the best. Don't let your "greed
glands" fool you; this baby delivers top notch performance at a fair
price. The competition, by contrast, sell extremely expensive sets of
snake oil lubricated transparent emperor's clothing. If you're after pure
performance then the A5CR preamp is for you.
| Very high quality phono
stage. |
MM and MC phono stage
with very low noise, accurate RIAA, wide overload margin and great
sound quality. |
| Dual mono. |
Better transient response
and imaging. Also greater depth of field. |
| Dual choke
regulation. |
Incredibly quiet power
supply, allowing the circuit to operate to its optimum. Also
excludes mains borne interference. |
| High current and voltage
output stage. |
Will drive any power amp
cable combination up to about 30 feet in
length. |
