Chip amps, such as LM3886, run very efficiently, and produce very little to almost no heat, even when cranked. They are NOT Class D (which doesn't sound "real" to me), but Class AB or B and sound excellent.
I owned BAT VK-60 monoblocks and sometimes could not use them in the summer (I have no AC). My electric bill was 30% higher when I did use them. The chip amps I have now sound better (yes, they do), and I leave them on 24/7 because at idle they consume a little more power than an alarm clock. I put my hand on the heatsink after a blowout session and it hardly feels warm.
I never need to replace a tube or a fuse or fiddle with bias (didn't with BAT's anyway, but you probably do). These amps will sound exactly the same every day until the PS caps fail in 15-20 years.
Peace,
