Perfect condition Pass Labs INT-25 Amplifier used only occasionally with my second HiFi setup. All original packaging , paperwork and remote control included . Any questions please feel free to contact me 7552223215 . I preferred picking up but delivery is also possible . Thanks
Excellent condition helps here: £4,750 looks like a solid buy for an INT-25, not a stretch. New pricing sits around £7,250, so this asks roughly a third off retail, which is right in the zone I’d expect for a clean used example; not a steal, but definitely attractive if it’s complete and genuinely well cared for.
The INT-25 is a lovely “less is more” Pass piece: pure Class A, very refined, very natural, and especially rewarding with efficient speakers and smaller-to-moderate rooms. It’s built like a tank and tends to hold value well, so a tidy example with the box, remote, and original paperwork is the kind of listing that rewards a quick, serious look.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
Pass Labs, an American high-end audio powerhouse, traces its origins to 1991 when legendary designer Nelson Pass founded the company in his California home workshop. Emerging from his earlier venture with Threshold Electronics, Pass pioneered prototypes of single-ended Class A amplifiers, enlisting collaborator Mike Burley to build custom CNC machines for production. The debut Aleph 0 model shipped in 1992, marking the start of a legacy rooted in pure, innovative solid-state amplification.
The brand focuses intently on a select range of components, excelling in power amplifiers, preamplifiers, integrated amplifiers, and phono stages, all hand-built in Auburn, California. Renowned for minimalist circuits and pure Class A topologies—often blending into Class A/B for efficiency—Pass Labs delivers exceptional warmth, detail, and realism. While they ventured briefly into headphone amplifiers like the HPA-1, their core strength lies in amplification, eschewing speakers, turntables, DACs, headphones, or cables.
Positioned firmly in the ultra-high-end market, Pass Labs commands reverence among discerning audiophiles and professionals for its uncompromising engineering, industrial aesthetic, and emotional musicality. Products embody technical precision with timeless simplicity, sustaining a reputation for quality and innovation that has endured over three decades, making them a benchmark for those seeking transcendent sound reproduction.
