PROst (PRO sound technique) was founded nearly thirty years ago.

We have developed about a hundred devices — from studio amplifiers to 16-kilowatt PA monsters,
from optical and FET compressors to tube preamps.

Our approach has always been rooted in the philosophy of classic, reliable, and ergonomic designs.

All elements undergo both instrumental and listening evaluation. In additon to modern, A-brands
measurement equipment, we use a audio-monitoring system with exceptional neutrality and resoluton.

This combination of technical and perceptual control allows us to precisely evaluate the subtlest sonic nuances.

PROst is not a factory — it’s a lab. A boutique where you can get consultaton, tailored solutons,
adaptaton, and customization.

We value not just sound, but aesthetics, engineering sensibility, longevity, and sincerity in the audio approach.
