Based upon this, I've un-stacked my Ultra Micro Amp from on top of the DacMagic. Both are a bit warm after a couple of hours of use, but not hot. The DacMagic is so much bigger that it makes the Ultra Micro Amp look weak, even though it is a fantastic amp, and there's really not much reason to stack it anyway.
