Manufacturer's notes
UL circuits typically need small amounts of feedback. As the Jinx utilizes the famed 6SL7 front end and 6V6 power tubes, rolling rectifiers became the upmost priority. Given its modest power output, and to make a tube rollers dream; the Jinx allows for nearly any 5V tube rectifier. This includes 5V4s, 5AR4s, 5U4s and the famous 5Y3.
At its core, the Jinx balance design decisions intended to provide silent operation, neutral voicing and ultra wide bandwidth. Tube choices that are common and yet avalible as very old examples without breaking the bank. Tubes known to be romantic while utilizing a circuit well intended to extract detail coaching enough power while demanding absolute silence.
The Jinx would be nothing without our custom transformers which our wound just for us. We default the Hi-Z @ 100ohms and the Low-Z at 8ohm. This is a perfect paring for both planers and dynamics alike. Give us your hyper efficient dynamics, you'll be rewarded with tone and s...
- Input impedance: 10K ohm with alps pot

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!

Our Summary
Product Strengths
- Delivers a holographic soundstage and exceptional mid-range clarity, creating a visceral and nuanced listening experience
- Offers great tonal accuracy and mid-range performance, especially with acoustic and vocal-heavy music
- The amplifier is powerful enough to drive speakers and the reviewer's headphones with ease
- Can be re-tubed with entirely NOS (New Old Stock) tubes for under $300, making it a bargain to maintain compared to other amplifiers
- Has multiple output impedances allowing matching to pretty much any headphone
Product Considerations
- Direct Heated Triodes are naturally more noisy than indirectly heated tubes
- Users with highly sensitive headphones (north of 100dB/mW efficient), like Utopia or Stellia, might experience some background noise
- Bass presentation focuses on detail and texture rather than thick, chest-thumping slam
- Caution should be used when lifting it, as it is much denser than it appears
Comparisons (according to reviewers)
- Vs ampsandsound Nautilus: The Rockwell is more delicate and nuanced, with more space and air, whereas the Nautilus produces greater slam and is more tonally dense
- Vs ampsandsound Kenzie Ovation: There are similarities in tone and vocal rendering, but the Rockwell is more powerful, creating dynamics that explode
- Vs ampsandsound Bigger Ben: The Rockwell provides more low-end detail, while the Bigger Ben reaches slightly lower with more slam
Takeaway: The Rockwell is a seductive and fun amplifier that is worth owning, especially for those who appreciate the classic American hifi sound. It offers a remarkable listening experience and the ability to use affordable NOS tubes.

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

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.
