/Nilai® Class D technology is here!

We have taken our existing control-loop topology to a whole new level resulting in an immense performance upgrade compared to NCORE®. The overall performance has increased by not less than 10 times!

This massive performance boost results in distortion figures that are 10 times lower, a power supply noise rejection that is 10 times higher and a reduced output impedance that has dropped by a factor 10. These figures may already sound incredible, wait until you hear them come alive through your speakers!

And today, 20 years after the launch of our very first Class D amplifier, we want to thank the DIY-community that has always been very loyal to us. Their support played a very important role in our company’s success. We therefore thought that letting them be the first to exclusively try out this new technology was the right thing to do! The Nilai500DIY comes with a discrete buffer stage and voltage regulators, just like the NC400 it will be replacing. Together with carefully selected high-grade components the Nilai500DIY is our best amplifier to date. Besides the amplifier we designed a new power supply to match. The PS500DIY includes a PFC and standby power supply. Just like on the Nilai500DIY we selected high-grade components for optimized performance.

DIY PreAmplifier

To complement our DIY amplifier modules we introduce our DIY PreAmplifier kit. Just like our amplifier kits you get a complete kit to assemble an analogue high-end preamplifier. Add-ons like a DAC, Phono stage and EQ will be released in the nearby future.

Custom-made doubly shielded twisted-pair cable designed specifically for highest RFI immunity and lowest microphonic noise. As we have set a new standard in performance with our Nilai500DIY and having a matching High-end PreAmplifier we demand the very best of our Interconnects.

More information about the Interconnects soon!
