About Us
The Home of NAT Audio
NAT is one of the most innovative manufacture globally in the segment of tube and hybrid
Manufacture NAT design and produce audio components of high-end class. The main manufacturing program includes vacuum tube and hybrid preamplifiers and power amplifiers. The main features of these products are triode configuration, short signal path, zero feedback in single ended concept. NAT "digging deep"! Looking for unconventional solution for the uncompromised sound reproduction!
NAT is one of the most innovative manufacture globally in the segment of tube and hybrid high-end amplification.

Mention models are the first commercial audio products globally in the class of their own.
Special attention in the process of fabrication is in the choice of parts that are assembled in NAT audio components. We are specially careful in the choice of tubes. When ever it is possible, New Old Stock (NOS) tubes of the worlds most famous manufacturers (General Electric, RCA, CEI Electron Tube, EI) are implemented. Most of them are also by military grade class.
NAT power amplifiers features special configuration of output transformer. Unique implementation of these single-ended output transformer provides extremely wide frequency response (example: power amplifier Transmitter has frequency response from 8 Hz to 110 kHz).
We would like to point out that all NAT audio components are hand made and that they are exposed to a rigorous burn-in test of over 100 hours for every single component before delivery to our customers.
