Inspired by a number of our clients who recommended that I try out the Pass Labs XA25 with our Sibelius loudspeakers, I finally got hold of a review model for my listening room. Here's what I thought of it.
Technical details and overview:
The output stage consists of a single pair of 800 watt new generation output transistors operating push-pull Class A. The result is faster, lower distortion, lower noise, higher damping and larger Class A operating envelope into low impedance loudspeakers, all in a simple 3 stage circuit with total of three pair of push-pull gain transistors.
Class A
Type Stereo
Gain 20 dB
Inputs RCA
Power Output /ch (8 ohm) 25W
Power Consumption (Watts) 240 (runs at around 40-50 deg. C)
Unit Dimension (W x D x H) 43 x 44 x 15 cm
