That seems excessive? 1.5 - 2x total wattage should be sufficient for most purposes. If it's for use in a pro setting, or really going to be running hot all the time, you might go up.
Most of the time you can figure 50% efficiency at best, so a 100 watt/channel
for a given load might draw 200 watts. On top of that, you would might want
some margin (around here an added 100% it seems) for 400 watts.
Two channels? 800 watts.
But for music you can get away with a lot less.
For Class A, assume the worst - idle dissipation x 2 for each channel.

Some time ago I got the LEDs I wanted, finally I am done with this amplifier 
. Also, the output RCA replaced with the "long" type - a better ground contact than the cheap ones from ebay and they better secured through the back plate IMHO .

Self has an optimum bias and Emitter resistance values for bipolar followers which
gives the lowest distortion number. Since it tends to be a fairly low current figure,
it has additional reason for some popularity.
This formula is limited to Bipolar devices in push-pull operation.
Pretty much nobody advocates lower bias or higher resistance values than these,
but some designers advocate higher bias and lower resistance.
