XA amplifiers

ver the years Pass has produced some

O

truly great amplifiers, each design unique
in some way. The XA power amplifiers offer
the marriage of two classic examples of
these designs - the Aleph single-ended Class
A output stage and the X Super-Symmetric
front end circuit. Each of these designs is
covered by basic patents and stands alone in
defining Nelson Pass’s simple but powerful
approach to amplifier design. Together, the
two topologies complement each other in a
way that represents a near perfect synergy,
resulting in the newest, highest standard in
audio amplification.

Compared to the X series, the XA
amplifiers have more emphasis on audio
perfection over power. Dissipating the
same power at idle, the XA series trades
efficiency for the warmer midrange,
sweeter top end, and better defined bass
of a pure Class A amplifier. If you need
raw power and very high current into a
low impedance load, an X amplifier is the
appropriate choice. If the purest quality
into a reasonable loudspeaker is your
choice, you want an XA model.

The XA series amplifiers run pure
balanced single-ended Class A with an

enormous bias current - they do not
fall back on Class AB operation. This
extraordinarily over-the-top Class A
is responsible for an effortless three­dimensional presentation of the sonic
landscape. This in combination with
exceptional resolution of minute detail
and dynamic contrast creates the illusion
that through these amplifiers you could
touch the performers, as if the last veil
was removed, but without a trace of glare
or harshness.

The XA’s retain the sweet warmth and
lushness of the Aleph series without fluffy
coloration, and the dynamic contrast is
