Debate: Class D amps need 48 hours of warmup


Have you listened to your amps cold? Warm? Both ways?  What was your experience? I’ll hold my own observations to not bias the replies. 

Did you leave them off while on vacation and then come back to find they sounded hard and strident?

The title, "engineer", has also been historically used to identify roles in certain industries where specialized scientific, mathematical, and technological knowledge are required, and in some cases these individuals are performing engineering related services but have not earned an engineering degree.

Don't forget trains!

@lanx0003 - no argument intended.  Just pointing out my experience that degreed engineers in some industeries are not required to carry professional licensure to perform engineering work.  I have seen this mostly with clients I have worked with in manufacturing industries (automotive, drug, food, etc.) but I would not be surprised that it could apply to @erik_squires for work with motion picture audio equipment, electrical/mechanical equipment, and installation.

It becomes murkier when folks who perform engineering type activities are referred to as "engineers" whether they have a degree or not.  I typically roll with that one as long as their work is not encroaching on areas where licensure is a requirement.  During college, I worked with an AE firm that had undegreed mechanical and electrical designers/drafters who were sometimes called "engineers".  They worked under the direction of a PE who would seal the drawings.  The industry seems to understand that a team of people are necessary to complete most projects and that not all are going to have a degree and registration, but those in responsible charge must have them.

A PE is absolutely required for engineers designing public works and structures, which is what I did for over 40 years (and still consult from my retirement) so I am currently registered in several states. However, @thecarpathian makes a good point - I am clearly not qualified to operate a train surprise

You were called out for saying that your "engineering knowledge and actual listening experience have not lined up".

That sounds like a fair statement. You didn't claim to be an engineer, and besides you don’t have to be one to have engineering knowledge, just like you don’t have to be an attorney to have legal knowledge. Just try and get sued!

Anyway, you were nice enough to dignify that pompous nonsense with a serious answer. I wouldn’t have. Maybe I’m not nice.
