Designed for high-efficiency speakers (93dB+)
Is it right for your system?
Works best with:
- High-efficiency speakers (93dB+)
- Full-range drivers
- Open baffle or horn speakers
- Simple analog listening systems
Not recommended for:
- Low sensitivity speakers
- Very high listening levels
- Large rooms requiring high power
If your system matches, the result is effortless and natural.
If not, this amplifier is not the right tool — and that is intentional.
Simple by design
No screen. No software. No unnecessary complexity.
Just a direct connection between your source, amplifier and speakers.
The Amp01 is a handcrafted Class A SET tube amplifier delivering 3.8W per channel, designed for full-range drivers, open baffle and horn systems.
Rather than chasing power, it focuses on coherence, tone and musical presence.
Handcrafted construction
Each amplifier is built by hand using point-to-point wiring and a short signal path, with individually assembled and tested construction.

Carefully selected components ensure stability, durability and consistent sound performance.
On the 6P1 tube
The Amp01 uses the 6P1 tube, a design often overlooked outside of China, yet widely produced and refined over decades.
Rather than following more common tube choices, we selected the 6P1 for its natural tone, balance and musicality.
Its broad availability also supports long-term serviceability, with a stable supply for years to come.
In this amplifier, the 6P1 is not an alternative — it is a deliberate choice.
Why low power
With efficient speakers, less power reveals more: clarity, nuance and a more direct connection to the music.
The goal is not loudness, but presence.
