In recent years, I’ve had more than a fair share of faulty PSUs, including melting and cracking of cases and cables (in one case, exposing live mains connection). The main culprit has been Cambridge Audio who have sourced obviously poor quality – and presumably cheap – units from China. Another is a fine high quality audio cable from Japan coupled with a USB cable whose plug split open on first use. I can get better quality at the $2 shop in town. Why undermine the brand like that? Not at all impressive!
