No I have not heard them, and agree they may sound great on the Devore speakers as they are reviewed as being a very easy load and can be driven by a "quoted" 9 watt amp.
On another forum a member measured the heat sink temp at 60c on a 23c day driving a pair Lennahan Audio ML-1 book shelf speakers at moderate level.

They have an impedance curve and phase plot that is quite easy to drive, they are a little low in efficiency, but not abnormal for a book shelf. Recommended amps are from 20-300w for this speaker, not as easy as the Devores but not very difficult either.
This kind of tested heatsink temp on a coolish day is too high, and the chassis forms part of the heatsink, which means the internal temp will be high also. Any increase in the ambient temp will increase the heatsink/chassis by the same amount. Electronics specifically capacitors won't like this kind of temp, and the junction of the output transistors will be even higher.
Cheers George
