01 / HARDWARE
Hi-Fi hardware
Amplifiers, DACs and speakers designed around measured performance, not marketing specifications.

Audio engineeringthat never wavers.
Stableton designs hardware, acoustic treatment and mastering chains built to sound the same in the studio, on stage and in your living room — stability first, character second.
Est. 2026Founded on the idea that consistency is the hardest problem in audio
3Core disciplines: hardware, acoustics, mastering
Studio & homeSystems built for control rooms and the rooms people actually live in
Measured, not guessedEvery design validated with instruments, not just ears
What we build
Precision you can see before you hear it.
Channel L
Signal path
Channel R
02 / ACOUSTICS
Room acoustics
Treatment and calibration that fixes the room, not just the equipment inside it.
03 / MASTERING
Mastering
The final pass that makes a mix translate, from earbuds to a full room system.
04 / CALIBRATION
System calibration
On-site tuning so what you hear matches what was actually recorded.
Why stability comes first
A system that flatters is a system that lies.
Most audio gear is voiced to impress you in a five-minute demo.
We build for the fiftieth listen, not the first.
A stable tone doesn't fatigue you, doesn't hide flaws, and doesn't change its story from room to room.
How we work
One pipeline, six disciplines.
Measure
Take the room and the source material seriously before touching a single component.
Design
Engineer the signal path around measured targets, not house style.
Prototype
Build and listen, blind, against the measurements — not the other way around.
Voice
The only subjective step, and the last one, once the numbers already agree.
Calibrate
Tune the system in the room it will actually live in.
Deliver
Documentation and settings handed over, so the sound stays reproducible.
Engineering notes
What we're working through right now.
Why "warm" is usually a measurement problem
Notes on what listeners call character, and what it actually looks like on an analyzer.
HARDWARE · MEASUREMENTCalibrating a room that changes with the seasons
Humidity, temperature, and why acoustic treatment isn't a one-time job.
ACOUSTICSWhat actually survives MP3 and back again
A mastering engineer's notes on what translates, and what quietly doesn't.
