High
Power
Output
with
Real
Phase
The
TX-108
and
TX-88
deliver
plenty
of
clean
power
even
into
low
impedance
loads,
and
have
lots
to
spare
for
effortless
handling
of
instantaneous
signal
peaks,
making
the
amplifier
sections
truly
the
equal
of
even
much
more
expensive
integrated
amps.
Both
also
Feature
Onkyo’s
exclusive
Real
Phase
for
clear,
accurate
stereo
imaging
and
extra
definition.
A
special
“In-Phase”
transformer
(in
addition
to
the
power
transformer)
“flattens
out”
the
charging
currents
in
the
power
supply.
Since
the
currents
are
no
longer
modulated
by
very
low
frequency
input
out-of-phase
signals
that
could
muddy
the
sound.
As
an
added
convenience,
the
back
panel
is
equipped
with
heavy-duty
speaker
terminals,
specially
designed
to
accomodate
both
single
and
parallel
banana
piugs
(TX-108).
