[QUOTE="juan, post: 878945, member: 2499"] My best experience with my small ZCA class a amp was with early model 120Watt old Mecer laptop charger as supply, then I used a 200w 24volt Meanwell it work but for some reason very thin sound and I noticed that the heatsinks does not heat up like the old laptop chargers. Then I order to new HP 120Watt chargers and thought they might be better than both and the same happened as with Meanwell that the heat sinks run cool as if the current was limited with some green power safe nonsense. I swapped back to the old Mecer big block switch modes and all perfect again ( heat sinks running hot ) but only 20v not 24v, I wonder what type of power supplies Nelson Pass is using because I could not get a constant current supply from two new switch modes ?
