Our take on the brand
An amplifier designed for the most demanding enthusiasts of 300B tube sound. The unprecedented PSE structure operating in class A was built using the highest quality toroidal transformers, designed especially for this amplifier. This guarantees linearity and wide frequency response. Extended tube life is ensured by delayed anode voltage switching. The unique tone of the 300B tubes is free, spacious and very involving.
Our summary
Product Strengths
- Neutral and transparent sound, more so than the reference amplifier
- Bass performance is remarkably tight, articulate, solid, and weighty, without typical 'tube character'
- Very good rhythmic capabilities
- Maintains control even with inefficient or difficult speakers
- Threads a fine middle path between a typical transistor sound and a typical tube sound—with an unmistakable midrange charm
Product Considerations
- Some might find it 'not characterful enough' because it is superbly even-handed
- With some speakers, the balance can be a little too lean and overly controlled
- Its low power rating ultimately imposes a limit on how loud one can play, which may not suit everyone
Comparisons (according to reviewers)
- Vs Ayon Spirit III: The Lybra sounds almost as powerful and robust in the bass while being perhaps even tighter and articulate, and is more highly refined with subtler and airier treble
- Vs Trafomatic tube amps and MP's Jadis amplifiers: The Lybra offers something different, it's not as voluptuous, rich, and relaxed as the Trafomatic
Takeaway: The Fezz Lybra is a neutral and controlled amplifier that offers a balanced sound without sounding like a typical tube amp, providing articulate bass and a charming midrange. It could be worth buying if you like very good sound, especially if you have efficient speakers.

The Little Nugget is meant to pair with the stereo pre and provide a no compromise entry into bespoke audio. With 17watts you can run nearly any speaker practically in most rooms. Fantastic pairings include JBL L100, KEF LS50, Tekton double impacts, Zu Dirty Weekend 6s, Klipsch Fortes, LS3/5a, Harbeth 30.1s.
The Stereo 17 (Little Nugget) is an EL84 ultra linear amp with 17 watts of tube bliss. 2 EL84 tubes in push-pull configuration per channel with 12AX7 for input and a 12AU7 for the phase splitter. The Stereo 17 is based on the famous Halfer circuit with cathode bias allowing trouble free operation. 8ohm and 4ohm taps with 8ohm and 16ohm combination as an option.
The circuit used is widely famed for its stability and liquid midrange. With fixed bias, tube rolling is a breeze. The removable tube cage protects your tubes when family and pets cant be trusted. The Stereo 17 produces perfectly stable 17 watts RMS with 22watt peaks.
The output transformers utilize massive cores which resist saturation and deliver jaw dropping low end performance. Like all ampsandsound amplifiers, it is dead quiet with reliable performance. When we say dead… we mean put your ear to the mouth of your horn-loaded system and all you will hear is silence!
Product Strengths
- Metal chassis provides better ergonomics and structural integrity compared to the previous wood chassis
- Robust power supply prevents compression, even with demanding speakers
- Has full bandwidth down into the low 20s without problem
- Warm lush midrange and the right 3d spatial cues up top
