Debate: Class D amps need 48 hours of warmup

Atma-Sphere class D monoblocks here as well. I leave them on 24/7 and do seem to have a slightly better more lifelike sound compared to when I used to turn them off. I do wonder if it affects lifespan of the components inside though? @atmasphere 

In my outdoor system I have a Bluesound powernode which is also class D. It doesn’t have an off or standby mode. I figured if that’s stayed on for the past 4 years and still works fine, then the Atma-Sphere class D’s should be fine as well?

No warm up required IMO.

@veerossi Not at all. 

Excellent. Thanks Ralph. I just want to say, love this setup. Using with Atma-Sphere MP-3. 

Now I am feeling guilty.  I used to be a Principal Systems Engineer working for Australia's largest company, but in reality I was a self-taught software guy with un-related degrees in physics and metallurgy.

Software development really only matured into a real discipline half-way through my career.  Even today, most software is developed using a debugging tool - the underlying expectation is that it will be wrong.
