Compared with the obvious alternative at this money — a newer, more powerful integrated or a mainstream solid-state power amp — £1,996 is on the steep side for a used F6 unless the unit is unusually clean, fully sorted, and nicely documented. The F6’s typical appeal is its cult status and DIY-friendly Nelson Pass pedigree, but used examples often trade more as enthusiast pieces than bargain-basement buys; without stronger condition or provenance, this price feels ambitious rather than a slam-dunk.
What makes it worth chasing is the sound: the F6 is a 25W Class A design that’s prized for openness, tone density, and easy musical flow with sensitive speakers. It can be a superb match if your system suits low-power Class A and you value refinement over grunt. At this level, I’d want reassurance on service history, originality, and whether any extras are included, because those details matter more than cosmetic perfection here.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
First Watt emerged from the visionary mind of Nelson Pass, the renowned American audio engineer and founder of Pass Labs, in the early 2000s. Established as a boutique extension of his primary enterprise, it was conceived not as a conventional company but as a personal laboratory for experimental amplifier designs. Pass launched First Watt to delve into unconventional territories overlooked by mainstream hi-fi, drawing on his decades of expertise in single-ended triode and solid-state innovations, much like the legendary early Marantz and VFET amplifiers that inspired him.
The brand specializes exclusively in low-power Class A solid-state power amplifiers, typically delivering 10 to 25 watts per channel into 8 ohms—modest outputs by modern standards. Models like the SIT4, F1, and F7 employ zero-feedback topologies, JFETs, Static Induction Transistors (SITs), and even current-source architectures that prioritize purity over brute force. These handcrafted units eschew preamps, phono stages, or speakers, focusing instead on driving efficient, high-sensitivity loudspeakers with exceptional transparency and musicality.
First Watt commands a cult following among high-end audiophiles as a niche boutique icon, revered for its heretical yet revelatory sound that challenges voltage-source norms. Positioned at the pinnacle of purist amplification, its amplifiers—often priced around $4,000—appeal to discerning buyers seeking "a handful of quality watts" over high-power generality, cementing Pass's legacy in the vanguard of innovative, speaker-specific hi-fi.
