There's no way that this could be a true 100 watt class A amplifier. The amount of heatsinking that would be needed to disperse the heat generated by a 100 watt class A amplifier is much more than the size of this amplifier. Not to mention all that heat would probably cook the electronics needed to run the CD player, tuner, etc.

Looking at the manufacturer's site, it says that this unit has a "100 watt Cool Class A amplifier". I have no idea what that means.

Possibly a PS Hybrid Class A (HCA-2) power amplifier.
Using SDAT amplification the output Mosfets are off much of the time
reducing a lot of heat build up.
