Pioneer SX450 BUZZ

I would only be heating the room with something like the Philips with my 1 watt or less listening habbits, but I do get it. I once had 100 Watts/channel into big woofers rocking out. These days I have a quality over quantity philosophy and I'm even moving in that direction with guitar amps.
 
Continuous power ratings are not common in Audio for a number of reasons but yes indeed the amps I was using can produce 100 Watts continuously. The point of having such a brute force power amp was based on handling low speaker impedances and keeping thermal cycling low without a fan. The 100 Watt bulb puts out the same power but works as a heater as much as a light source. Fortunatley audio amplfiers manage to convert a fair amount of that energy to mechanical force and waste less as heat.
