The 432 is very sensitive to power supply. I use it with B&W 802s and the 390S as CD/Pre. After run-in of more than 350 hours, I found the sound disappointing and wanted to change the amp. Learnt about the importance of power supply, and after installing a dedicated spur to a passive line filter and a quality heavy gauge shielded power cable, the result was astonishing! I don’t plan to change the 432 any more and instead have experienced this amp to deliver a truly exceptional performance with remarkable precision. I’ve heard other systems that are more expensive but sonically were inferior.
