Tabl10s,
I recently bought this amp a coupla weeks back. Since then it has been on 24/7. As John points out, leaving it on and in AB (draws < 40 watts) is the default way to go...but when you really want to listen into the recording, I find that only after 30 minutes of class A bias, it has reached near its nominal heat and sound. Not sure about days of class A bias nonstop. It might be marginally better but at 500 watts continuous I'm not paying to find out :)
With my ears/system I get pretty much the peak sound within an hour. It is a marvelous amp. I am totally thrilled with the integration of it with the rest of my gear. I've said this before but I really feel this one is a "keeper" ;)
