SW1X Integrated Amplifier Products Overview

SW1X Audio Design® Range of Integrated Amplifiers

It is all about Quality and not Quantity.

All of our Integrated Amplifiers are Pure Class A Valve Amplification with Zero NFB and most of them are Single Ended, producing therefore super Quality 2-8 Watts of power, which sound like 20-80 Watts when paired with with High Sensitivity Speakers (min 96dB/W/1m is recommended), where damping and dynamic delivery feels like 200-800 W

Being Valve amplifiers operated in Pure Class A, Single Ended mode without any kind of feedback, the circuit design is as elegantly simple as it can get.

Therefore, the quality of amplification is almost entirely dependent on the factor of Quality of Materials & Componets employed in the circuit design.

SW1X Performance System

All our Integrated Amplifiers are offered in 4 versions:

STD, all Copper wound, orient grain M6 EI Core OPTs
Special, all Copper wound Super HiB DC Core OPTs
