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!

For grins I decided to try a Crown XLS1500 that I have (it was powering pro/pa speakers in my jam studio). It's a class d 300 watts at 8 ohms. I didn't think it would fit through the cabinet door because it's 19" wide, but I managed to squeeze it in on an angle.

in any event, it powers the Sttafs really well and sounds surprisingly good.  Better bass than the st140 and very nice up the spectrum. It runs cool and has built in fans if needed (likely won't). So I'm going to run with this for now and see how it performs with more music play. I already ordered a replacement for the studio, and the st140 will be listed shortly along with my eagle 2c prime.

thanks everyone.

@bdgregory IIRC that amp has a programmable menu. Go into the menu and shut down all the DSP functions and the like. You may notice it sounding even better.
ok, there's no DSP, just crossover and bridging modes. I had already bypassed all of that.One thing I did do is tune the gain controls (which I originally assumed were attenuaters) which helped a little. 

I'm very, pleasantly surprised by this little amp.
