Pass Int-25

The Pass Labs INT-25 is an integrated amplifier that perfectly demonstrates why Nelson Pass has been among the most respected designers in the high-end audio world for decades. Despite its modest declared power of 25 watts per channel, the INT-25 delivers an impressive control, dynamics and musicality that makes much more powerful amplifiers effortlessly forgotten.

 

The fully pure Class A amplifier is based on the famous XA25 power amplifier, supplemented by an extremely minimalist preamplifier section. Thanks to this uncompromising construction, the signal path remains exceptionally short, resulting in a highly transparent, natural and flowing representation.

 

What immediately stands out is the relaxed presentation. Music separates from the speakers, voices sound tangible and instruments get natural warmth without compromising on detail or speed. The INT-25 combines a rich sound colour with impressive spatiality and almost effortless control over the entire frequency range. Especially in combination with loudspeakers from medium to high sensitivity, this amplifier manages to create an extremely convincing and emotional listening experience.

 

Like all Pass Labs amplifiers, the INT-25 is built to the highest quality standards. The heavy aluminum housing, generous power supply and high-quality component selection not only provide excellent performance, but also exceptional reliability and timeless design.
