The
'Basis' provides a silky smooth, clean, 
dynamic presentation with low distortion
using a Class 'A' zero feedback circuit
providing a low output impedance and high
input impedance. If you have
never heard the virtues of a 6SN7 based
preamp, especially one designed by Purity
Audio Design, you do not know what you are
missing. Don't let
the affordable cost or simplistic design of the Basis MKII fool you,
this is a piece that is very much at home in
the most elaborate audiophile systems and
decors. This affordable tube preamplifier
maintains the dynamic quality of all types
of music. You have the option of running
6SN7 tubes or with our adapters, you can run
12AU7 type tubes with no more than simply
installing the adapters.






The sound of
the Basis mk2 is has a better sense of
refinement and dynamic impact at the
frequency extremes with a kiss of emotional
warmth. Like all Purity Audio Design products, the Basis
mk2 provides a dead quiet background allowing you to
enjoy and appreciate the finest nuances hidden within your
recordings along with a broad soundstage positioning you in
the center of the performance.




The Basis mk2
a GoldPoint step attenuator, 4 line level inputs
and two
sets of RCA outputs that are perfect for bi-amping
or driving a powered subwoofer. 
A standard feature in the Basis mk2 is a
newly designed choke filtered power supply
for
a background as black as the deep reaches of
space. A new highly regulated supply is now
implemented for the tube
heaters/filaments.




The circuit design places very little stress
on the tubes assuring extremely long service
and sonic life of the tubes. Quality, Value,
and Performance, by Purity Audio Design and
like all Purity products, hand made in New
York, USA.
