Good!
As a point of information, though, your Melody SP3 is a class AB amp, and the power it draws will therefore fluctuate with the dynamics of the music, and will be much less than 350 watts most of the time. While the power consumption of the class A biased LM SET amps will be essentially constant at all times.
What will be converted into heat by the LM amps will be the power it draws from the wall outlet (nominally 400 watts) minus the power it delivers to the speakers (which is likely to be just a few watts most of the time, or even less). It’s a different story with class AB amps.
