I owned the 532H it is completely dual mono. There are toroidal transformers and filter caps for each channel. Its design was derived from a Proceed amp with improvements to the power supply which also located the caps on the amp pc/bd.
Aside from the possibility of a failure this amp benefits greatly from being left on 24/7 and the use of a high-end power cord. I used Nordost or Shunyata.
