Condition is mint, which is exactly what you want in a 300B amp and it helps justify the ask. At US$3,049, this sits a bit above the US$2,678 median for recent comps, but still below the US$3,986 75th percentile, so it reads as fair-to-slightly-ambitious, not overpriced.
The appeal here is the 300B topology: if you want rich tone, dimensional mids, and that easy, spacious presentation, this is the kind of integrated that earns its keep. A clean example in black finish is especially attractive if it’s complete with remote, box, and documented tube hours, because premium tube amps tend to hold value best when they’re carefully kept.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
Fezz Audio emerged in 2016 from the established Polish transformer specialist Toroidy, which boasts over 30 years of expertise in toroidal designs and holds three patents in the field. Based in Kolonia Koplany in northeastern Poland, the brand was founded to channel this heritage into high-end vacuum tube amplification, marking a bold pivot from power supplies to complete audiophile systems. Over 80% of its components are produced in-house, ensuring meticulous control and innovation rooted in Poland's growing reputation for precision hi-fi engineering.
The company focuses primarily on tube amplifiers, including integrated models like the Silver Luna Prestige and Olympia, which deliver robust output such as 80 watts per channel with modern quiet operation. Their catalog extends to preamplifiers, power amplifiers, phono stages, and recently, the Equinox DAC—their first foray into digital-to-analog conversion with versatile optical, coaxial, and USB inputs. What sets Fezz Audio apart is its pioneering use of toroidal output transformers in single-ended amplifiers, the first of its kind worldwide, blending traditional tube warmth with optimized power coupling.
Positioned as a niche boutique in the high-end market, Fezz Audio earns acclaim for transparent, emotional sound reproduction that prioritizes musicality and clarity without excess. Distributed across Europe, Asia, Africa, and North America, it appeals to discerning buyers seeking value-driven excellence—handmade Polish tube gear that rivals pricier competitors while delivering purist performance and striking design.
