Ex-Dem Pass Labs INT-25 Integrated Amplifier
One unit ex-dem with remote and box
At Pass Labs we 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. They measure well, sound great, and are reliable. Twenty plus years of ongoing innovation have kept the X and XA amplifiers at the forefront of high-end audio.
The INT-25 embodies all this and less. A smaller stereo Class A amplifier at a lower price, it 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, “that other negative feedback” in all stages.

Ex-Dem Pass Labs XA-25 – Stereo Power Amplifier
1 unit ex-dem with original packaging
No other offers apply or can be used
The new XA25 offers great sound at slightly lower power, without frills, at a lower price. It embodies new components and innovative circuits coupled with the best elements of the previous generation.
Degeneration, “the other form of feedback”, has been eliminated. 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.
Ex-Dem Thivan Labs 211 Gold Swan Integrated Amplifier
- 1 unit ex-dem
- Please enquire for shipping cost if outside the UK
- The SWAN 211 Single-ended version’s sound quality is similar to that of the 211SE Anniversary version (the 2-blocked type). However, it is beautifully designed to be contained in one neat amplifier block. This one-block design, compared to the 211 SE Anniversary series, enables the Swan 211 to easily fit in narrow spaces.
