SA-01 Stereo Power Amplifier (500W)

Description

Building on the success of our multi-channel Hypex NCORE® MA-01 amplifiers, we are introducing a stereo amplifier – the SA-01. The MA-01 was built with pure utility in mind, where form followed function. With the SA-01, we have allowed ourselves a little more freedom in the design of the case work to bring you something more at home in an audiophile HiFi system, where if will take pride of place on your equipment rack. As customers often employ phono connections and cables for audiophile  systems we have introduced phono connectors alongside the XLR connectors with a high quality sealed switch to allow you to choose your preferred connection type.

This version of the SA-01 comes with an 8mm milled aluminium fronts in cool anthracite and is built around Hypex’s NCORE® NC122MP amplifier module, which features highly efficient switch mode power supply and a high-performance, low noise Class D amplifier on a single board.

The SA-01 includes all the advanced  operation you have come to expect from KJF Audio and the MA-01. Value is still intrinsic to our brand and we have bought this to you at a great price again.
