The Pure Sound P10 is compatible with moving magnet
and high output moving coil cartridges. Low output moving
coil cartridges will require the use of an additional
step-up device or matching transformer. Full output
from the P10 is sufficient to drive the line level inputs
of any integrated amplifier or pre-amplifier.
active amplification stages use double triodes in a
simple anode follower configuration. The phono equalisation
is achieved using passive components and can therefore
maintain its accuracy over time without introducing
the unacceptable levels of phase shift found in active
equalisation stages. There is no negative feedback in
P10 features a particularly elaborate HT power supply.
After the initial rectification and smoothing, the supply
is split and two separate, heavily decoupled high voltage
rails are established. These feed each half of the output
valve while further decoupling of each rail allows the
cleanest and most independent voltage rails possible
to feed each half of the input valve. The absolute stability
of this supply regardless of the demands made by the
audio signal on the circuit, lends the P10 a stability
and poise which allows effortless reproduction of the
most demanding source material. The valve filaments
are also fed by a DC supply thereby ensuring constant
operating conditions for the amplifier.
circuit makes use of close tolerance metal film resistors,
polypropylene signal coupling capacitors and selected
gain of the P10 is 40 dB (x 100).
P10 phono amplifier meets the very strict performance
criteria required of all
Sound products and will give excellent results with
vinyl records provided that it is used with appropriate

The P10 Phono stage was awarded the top accolade of
5 globes in the February 2008 edition of HiFi World.
"... it had me reaching for LP after LP in night
long sessions. It's a product that is very right, one
that draws you into the music....
...one of the best phono stages around..."
