Pass Labs XP20 Pre Amplifier Hi All, I purchased this preamplifier from the forum years ago - but no longer require it as I have moved to a digital only system. Have done some price research and they seem to be selling for ~$4,000USD, so I think given the unit is upgraded with all the fancy EMI treatment, that it offers good value. The prior ad is very detailed - and this time around I'll be including a Tortech step down transformer, which hasn't skipped a beat. Attached a couple of fresh pics too. Happy to demo the unit with some Tad ME1s - it is silent and works well. Conditi
Notable because this is a respected high-end preamp, and the asking price sits a bit above the middle of the current used market rather than at a true bargain level. Against 37 recent AUD comparables, A$4,250 is above the A$3,544 median and still well below the A$8,597 75th percentile, so it reads as fair-to-mildly ambitious, not cheap.
That makes sense if the unit is clean, well-kept, and complete, because the XP20 is valued for its very quiet, transparent line-stage performance and strong system flexibility. For a buyer, the upside is in condition, service history, and included remote/power supply/cabling; if those are all in order, this is still an attractive way into a classic Pass Labs preamp rather than a risky stretch.
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.
