The FTC may consider dropping the Amplifier Rule.

History seems to be repeating itself. What was once widely known has gradually been forgotten, only to be rediscovered or reinvented later. It's as if there’s a generational memory gap, where each new generation has to repeat the mistakes of the previous one in order to reach the same conclusions.

Strange, isn’t it?

You sound like you're as old as I am!
The rediscovery thing only really bugs me, I guess, when it's branded as innovation.
Sort of like that Dynaquad-in-a-Schiity-box, with some more knobs and buttons thrown in -- touted as a future proof resource for the multichannel listening experience.

I assume that's a rhetorical question and you're old enough to have observed this normal cycle many times.

It is. I still find it strange though.

A function of modern communications and the internet.

The more complicated things get, the more the general population doesn't understand; forcing them to rediscover the purpose of something more educated folks previously established as fact and that simply takes longer than it used to.

I highly doubt this cycle will subside. In fact it will probably get worse the more advanced technology becomes.

A forum like this should advocate for meaningful measurements, not simplistic easy-button single numbers that don’t trace to actual use cases.

I think long burn-in times at 1/3, or 1/5, or 1/8 power is very meaningful because it tells me something about reliability.

There are use-cases for specific components. The problem with consumer goods is some have higher expectations than others, there is no perfect mark everyone agrees on. That is the reason for generic language.

Honestly I don't really care this much to spend so much time making the same point. Engineers always gripe when laymen say something or make a law they don't like, ignoring the fact that all engineers themselves don't agree. Then magically, engineers always solve the problems they originally griped about. Round and round we go.

While I understand your point, you unfortunately used a subjective term here

We can already solve the problem with sticking fans in every amp to pass some version of FTC rule. It will make amps larger, potentially noiser and more expensive. Is this what you want?

Exactly, it has been happening anyway regardless of FTC rules. Even an AV preamp processor with tons of internal space like Anthem's have fans that actually tuned on to the point many complained lol... Denon/Marantz AVRs have been using multiple fans for a few years now, but they may be there for the 5 minute tests, who knows?

The tests I advocate are not subjective.

Engineers in standards working groups don’t always agree, but they take a vote if they have to between competing alternatives that are all better than some simplistic number that confuses rather than clarifies the market.

I’m not guessing.

"Meaningful" is subjective.

 

[rdenney]

Rubbish. “Meaningful” means the measurements are important to the application, not some simplistic arbitrary number that does not tell a potential buyer which amp might make music louder (which is an entirely measurable objective). There’s nothing about being meaningful that requires subjectivity.
