is a hybrid amplifier
using a 6922 input tube buffer
has taken the Harmony
stand alone buffer
and incorporated it as the input
stage for a
hybrid amplifier by mating it to
one of the most advanced Class D
amplifier technologies currently
ΜΟΥΣΙΚΗ's output stage is
based on one of the most
advanced Class D Technologies
currently available. The AMS

Bostrom, founder of the design
house Anaview AB in Sweden.
dynamic 170 watts into 8 ohms,
300 watts into 4 ohms and 500
watts into 2 ohms.
6922 input stage is comprised of
a single 6922 per channel.
Inputs consist of one set XLR balanced and one
set RCA single
ended outputs. Both balanced and single ended are transformer coupled
using custom transformers design for Purity Audio Design. The
link between the tube buffer input stage and amplifier section is
handled via another pair of balanced
transformers taking the single ended output of the input tubes
and converting it back to balanced prior to entering the
chassis you will find that Purity Audio Design
continues it's tradition of using only the best parts including
first rate input and output balanced transformers, Top grade
Clarity Cap MR and V-Cap TFTF capacitors
and silver plated Cryogenically treated wiring. Like our other
products, you will not find a circuit board in sight other than
the independent dual DC regulated power supplies for the input
heaters. Both the
power supply and analog circuit utilize 100% point to point
The all important circuit contains what we have
found to be the best combination of passive components to bring
the Harmonia alive. High quality DynamiCap output capacitors
from the tube stage. The Input tube stage itself is comprised of
Clarity MR and V-Cap TFTF capacitors There is also the
option of having the output capacitors bypassed with smaller
value, Reference Grade V-Cap TFTF capacitors to maintain air and
Purity Audio Design products, the
utilizes a hearty
power supply for the tube input stage. Starting with the high current
toroidal transformer to the fully regulated DC filament supplies for
each of the
tube filaments, the power supply is designed to perform.
The main B+, filament supplies are all
each powered by separate, high current transformer taps.

for a vibration free chassis.
