What is the difference in audio quality of UcD® and Nilai® DIYclassD amplifier kits?

Nilai® represents Hypex's leading technology, often utilized in high-end applications. With Nilai®, we have advanced our existing control-loop topology to an entirely new level, resulting in a significant performance upgrade compared to NCORE®. The overall performance has been enhanced by a factor of ten. However, UcD® products are also highly respected in the audio community and are already considered to be of audiophile quality.
