The Puresound 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
Puresound 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 Puresound 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 Puresound P10 is 40 dB (x 100).
Puresound P10 phono amplifier meets the very strict
performance criteria required of all Puresound products
and will give excellent results with vinyl records provided
that it is used with appropriate ancillary equipment.
World February 2008
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..."
