Inovative Audio Manufacture


Reference Zero Feedback Balanced Line Stage

Magnetic is a newest reference point line stage made by NAT standards – transformer coupled, class A with zero feedback circuit configuration. Special selected vacuum tube is used - represent high technology in industrial tube manufacturing.



Magnetostat Se

Reference Absolute Zero Feedback Vacuum Tube Line Stage

Our flagship linestage!

Magnetostat Se set new reference point for the line stage device made by NAT as transformer coupled pure triode class A with absolute zero feedback circuit. Special military grade type 6S46G-V (tiny unique tube with lowest internal impendance) output tubes are used.




Se1 HPS Single - Ended Mono Block Power Amplifier

After 24 years from the first production (from 1999.) of Se1, newest version Se1 HPS  rapidly improve quality of all previous models! Power output is set to max. 60W (instead of 25W from previous Se1 GM70 model). Special single voltage gain stage design is implemented. Single-Ended Mono Block Power Amplifier Se1 HPS (Hybrid Power Supply) has very short direct signal path - without main coupling passive components - no any coupling capacitors & no any inter-stage transformer(s).


Transmitter HPS

Single Ended Mono Block Power Amplifier

After a several years in production NAT revised (from November '19) a real high-end amplifier-Transmitter HPS (Hybrid Power Supply).

Transmitter HPS is a reference point power amplifier made by NAT as pure class A, single – ended type with zero global feedback circuit configuration.


Single HPS

Single Ended Integrated Amplifier

After a few years in production NAT revised a real high-end integrated amplifier - from Single to Single HPS (Hybrid Power Supply)!


AC Coupler Black Signature

High End AC Power Cord

AC Coupler Black Signature is made to supply clean power to the low to high consumption analog or digital components. Construction is based on special semi-shielding and hand assembled geometry technique with ultra low capacitance, inductance and resistance! Design is implemented without any additional discrete passive electronic component. Each Black Signature cable takes several hours to complete. Dielectric of internal wires: Air based. Conductor type of internal wires: special treated OFC with other material.
