Debate: Class D amps need 48 hours of warmup

I do wonder if it affects lifespan of the components inside though?

@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.

Honestly you guys are far too kind.

Having an engineering degree doesn’t entitle its bearer to demand others list their credentials just because they had the audacity to use the word "engineering" in a totally unrelated context / field.

That’s pretty minor as bullying goes, but bullying is not OK, here or elsewhere.

At least @mitch2 proves that not all licensed engineers are humorless 😄

@oldnslo  : 

Serious and not intended to be inflammatory question:  do the electronics on NASA missions require hours or days of warmup for optimum performance?  Does anyone know? 

Sometimes! The optics and electronics on the James Webb Space Telescope took weeks before they could even begin to calibrate them.
