- Delivers rock-solid image placement and transparency, particularly in the midband
- Acts like a higher-wattage amplifier than its 18W rating suggests
- Can drive speakers that aren't absurdly sensitive
Product Considerations
- Build quality is not as refined as the more expensive Japanese-made Audio Note products
- Bass can be waffly/uncontrolled
- Top-end frequency performance can vary

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.

Our take on the brand

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
- Fast, accurate, proportionate sound that is warm but not dry or analytical
Product Considerations
- The reviewer mentioned they are going to work on adding name badges to the next versions
Takeaway: The amplifier is great sounding with a robust power supply. Its proportionate and warm sound makes it ideal for nearfield listening.
Video review
Our take on the brand
Product Strengths
- Creates an extraordinarily vivid sound
- Has the seeming ability to turn up the contrast knob on everything passed through it
- Offers great color and body
Product Considerations
- When playing very loud passages at extravagant volume levels, it clipped less elegantly
- Bass output was just a bit excessive
Comparisons (according to reviewers)
- Surpasses the Haut-Brion in terms of color saturation
- The Haut-Brion has a somewhat better sense of scale overall, is capable of greater delicacy when needed, and sounded a shade righter, timbrally, on trumpets and singing voices
- The Haut-Brion offered the more well-balanced bass, relative to the volume of sound in the rest of the audible range—the Haut's bass was also drier and a little more detailed
Takeaway: The Shindo Montille CV 391 is a hand-wired tube amp that delivers vivid and colorful sound, making music come alive. It's a great match for less sensitive speakers and offers a unique listening experience.

Our take on the brand
Our Summary
Product Strengths
- Uses a Static Induction Transistor (SIT), which has characteristics similar to a triode vacuum tube
- It expands and opens up soundstage, with a gorgeous sound and great midrange, with voices sounding present and full-bodied
- The amp holds a conversation with the speaker, letting it 'have it your way'—rather than forcing its own sound
- It's spectacular on tone complexity, spatial hydration, fleshiness and vividness, making it sound off-charts organic, elastic and tangible
- The main aspect that positions it noticeably above all other amps is immersion, making music three-dimensional, material, enveloping
Product Considerations
- The SIT-4 is a limited production piece due to the limited availability of the Tokin SIT transistors
- The power output is limited (10 watts into 8 ohms, 5 watts into 4 ohms), so it's not a universal amplifier
- It is not ideal for speakers that require a lot of power, like Magnepans or electrostatic speakers
- The power switch is located on the rear of the unit
- Runs very hot
Comparisons (according to reviewers)
- Vs First Watt SIT3: It sounds cooler in tonal balance and has more 3D imaging and body
- Vs Pass Labs XA-25: It sounds more immersive, while the XA-25 is sharper and more focused
- Vs First Watt F7: SIT-4 felt more gathered, punchier and texturally juicier, the F7 was more diffused, innocent, icier, leaner and color-wise opaque
- Vs Elekit TU-8900: It is more rugged and expressive, while the TU-8900 presents recordings more aesthetically
Takeaway: The SIT-4 is a specialized amplifier that produces great sound with the right speakers, with beautiful tone and expands the soundstage. It's a good option for people who like tube amps but want a solid-state amplifier.
