Fezz Audio Lybra 300B Integrated Amp White (Demo)

Pure 300B Magic. Like New. Priced to Move.

The Fezz Audio Lybra 300B is one of the most musically compelling integrated amplifiers available at any price. Built around the legendary 300B output tube in a PSE (Parallel Single-Ended) Class A configuration, the Lybra delivers 2×15 watts of effortless, bloom-rich sound that draws you into the music and keeps you there.

This is the original Lybra 300B in a stunning White finish — like new, in our warehouse, and available for immediate purchase or local pickup. Priced at $4,500, you save $2,495 off the $6,995 retail price.

Why the Lybra 300B?

The 300B triode is the gold standard of tube sound — free, spacious, and deeply involving. Fezz Audio's PSE topology runs two 300B tubes per channel in parallel, delivering more current drive and lower output impedance than a standard single-ended design, without sacrificing the harmonic beauty that makes 300B amplifiers so addictive.

The 6SN7 and 12AX7 input tubes are carefully matched to complement the 300B's character — adding dynamics and impact while preserving the midrange magic. Custom-wound toroidal output transformers ensure wide frequency response and exceptional linearity. Autobias keeps the tubes operating optimally without manual adjustment.
