Nilai DIY Preamplifier Kit

Gain up, noise down, the DIY PreAmplifier.

To complement our DIYclassD amplifier kits we introduce our brand new DIYclassD PreAmplifier kit. Just like our amplifier kits you get a complete kit to assemble an fully analogue high-end preamplifier. Add-ons like a DAC, Phono stage and EQ will be released in the nearby future. Because of it’s modular design, add-ons can be added at a later stage after you have finished building your analogue DIY PreAmplifier.

Build yourself a state-of-the-art high-end preamplifier with this DIY kit by DIYclassD. DIYclassD is part of Hypex Electronics. At DIYclassD our aim is to serve the global DIY community and consumer market for Hypex products.

With the easy to follow instructions you will be able to realize a high end preamplifier at a fraction of the cost and all of this can be done in just 30-60 minutes. Combined with our DIYclassD Nilai® power amplifier kits you can create a complete set of superbly sounding equipment.
