At Pass Labs they build Fet amplifiers with excessive output stages, huge heat sinks and massive power supplies. We use the highest quality components in simple linear topologies, assembled and tested with care and subtlety in Auburn, California. They measure well, sound great, and are reliable. Twenty years of ongoing innovation have kept the X and XA amplifi ers at the forefront of high-end audio.

Pass Labs XA25 Class A power amplifier

The XA25 embodies all this and more. A smaller stereo Class A amplifier at a lower price that takes advantage of the lower power requirements to have simpler single-ended circuitry and fewer parts in the signal path. This also allows elimination of degeneration. Simpler and fewer gain stages improves speed and stability. Lower voltages means the ability to run gain devices at higher bias currents, more deeply into Class A. Newer power Fet technology replaces banks of parallel small transistors with a single pair of industrial devices, each having a 700 watt / 40 amp rating. With no current-hogging issues and a new constant-current bias circuit to compensate for temperature drift, they connect directly to the loudspeaker without ballast resistors for the lowest possible distortion and highest damping factor. No degeneration also increases the efficiency and Class A operating current, allowing greater Class A operation into low impedance and reactive loads. The simple front end circuit uses uses two pairs of NOS complementary Fets in common-source mode in a current feedback (CFA) configuration. The amplifier is direct coupled and has no DC servos or frequency compensation.

New life into the music

As with all Pass amplifiers, the technology and construction are strictly in the service of the listening experience. The XA25 measures superbly, but its subjective qualities are most special. In an industry where products with great specs are often found to be dry and boring, this amplifier breathes new life into the music.
