The nxV200 VFET-MOSFET Audio Amplifier Module is a very high performance, high end audio amplifier module which is biased into Class A/B.

Hundreds of man hours has gone into its research and development.

Don't be fooled by it's small size and use of SMD components, this is the best sounding and well engineered amplifier module on the planet in it's power rating.

Many hundreds of these modules have now been sold to very happy customers, not one of these clients that we are aware of has not loved the build and sound quality of this amplifier module.

Read the Testimonials and have a look at the Gallery and see for yourself what some of the those who have purchased the nxv200 amplifier module are saying.

If you are looking for something even more simple to put together, please have a look at the HPA-nxV201ps module, it is based no the nxV200 and has its own high quality low noise power supply on board.
