Cool running amplifier

I'm looking for an amplifier to drive Totem Sttafs in my main great room. It will be housed inside a cabinet - ample air around it and ventilation from the back, but since I want to leave it on 24/7 I want one that idles cool.

budget is <$700 for a used power amp or integrated. I have in mind a musical fidelity a3.x, or ps audio hca. Do these fit the bill? Any others that I should look for?  

Thanks!

Hypex nc252mp-based designs are incredibly good value, with lots of clean power, and cool, low power consumption.  Like these:

Or get a Yamaha AS series if you want AB.

Sunfire symphonic reference power amplifier, 250 watt 8ohm doubled to 500 watt 4ohm. Auto input signal turn on is a nice ’set and forget’ feature, Load invariant technology which allows the amp to put out tremendous amounts of power while generating almost no heat.

Amps in cabinets is generally a bad idea unless provision is made for cooling. Even class D amps (the coolest running made) will make heat when you push them! Heat leads to failure so I would think about how to make the cabinet more amplifier friendly.
