Two Class A units produce a lot of heat.
Very bad idea.
Stacking pass labs power units??
Currently have an xp-22 preamp with separate power supply. It currently sits on top of the supply. Getting the xp-27 this week which also has a separate power supply. I'm wondering, can the power supplies be stacked on one another while the preamp and phono stage are stacked. I don't have much space, so something has to be stacked. Thoughts?
