Just for fun, I look at the claimed RMS output on these class D amps, then look for a spec label on provided wall wart power supply. This tells me how much they are lying.

If they are getting severe distortion at 1 watt, that tells me that they are running the preamp tube WAY too hot.

Well said lady, now only those noob youtubers who don't know what they are saying or are keeping quiet about this paid stuff. They should put class g/h back on the market, with the d mixed in between, a/b sucks away too much power

Glad the FTC revised the standards and really glad you did a Monday Monologue on it!

Your very right. Thank you.

Never going to happen, the bean counters at companies will not cooperate, they'd rather gamble and generate cash. So what is needed is outside expert measurement for products sold in the US. Company pays for the testing, done by a government sanctioned tester. Without mandatory unbiased testing regulation is just bureaucratic hot air.

Monday monologs are the best videos on youtube.

Stuff on Amazon is half the time not even UL listed.

They should also make builders produce a SNR of 110db.

This only part of the problem as you well know however, even more so with certain Credit Card and Pay apps. Don't even get me started on the stupidity of this KZfaq Yard Ape problem...

Great video Steph. ChiFi crap. You're a sucker if you buy that garbage. A fool and his money are easily parted. I laugh at simpletons that buy this rubbish. Too bad your average 'tube connoisseur' is a half-wit. I bid you a good day.

The new regulations are likely to mislead consumers for tube amplifiers, especially single-ended ones.

I remember when mainstream brands started citing "peak music power". We then got boom boxes and midi-systems advertised with "2000W PMPO" meaning it hits 2000 watts for a fraction of a second at huge distortion levels. Technically true but in real world use a lie.

My amp makes 0 watts into 8 ohms @ *3.7 % THD. Your absolutely Right. Gotta think. I like. RMS. ❤️

I always look at the plate on the back. The power out cannot match or exceed what goes in.

Yes! This needs regulation. Poor suckers like me and others purchasing products and believing the bs specs only to find out they under perform. Does this mean you won’t be finalising the mp301 mods? I bought two to run mid and high compression drivers in an active set up. Didn’t sound great running shuggie -z kt88 full range with my passive crossovers in the speakers. No bass and thin sounding.

Now if we could just get a similar standard for loudspeaker manufacturers for speaker efficiency ratings and frequency response.

Yes! This is certainly good news. Just think of how many people bought amps to match their speakers, only to find they make a terrible combination. Hopefully, this will be the beginning of the end for all those BS ratings. There’s so many products out there held under strict guidelines. Why should HiFi be exempt and get a free pass? Enjoy your break and recharge those batteries. We’ll all be here when you get back. Thanks, Stephe!

Harman-Kardon lost a lot of sales during the power wars era because they wouldn't exaggerate their specs. The more things change, the more they stay the same.

Are these watts peak watts, or watts measured as the RMS values of the current and voltage values presented to a resistive load at the point of clipping (distortion % figure) of a sinusoidal test input waveform? IE the so called RMS watts? The watts need to be properly defined.

Folks who watch this channal or ther others who regularly perform the THD+N vs freq vs. power in Watts know anyway that the rated power cannot be trusted. If the products are tube powered, the consumers know their ballpark power rating from the power tube numbers anyway. For example, you can'y expect to get 20w/ch from purely single 300b power tube.

Went through this in the70's when I was a kid selling stereos. The FTC had only one job.......

Good on you Stephe. The truth always wins out over deception

Tough to enforce. Would add too much cost. Amazon sellers are the grumps prob. None of us like it but...who knows. Love your work. Dont dissapear!

Audio fans will decide through listening to the music using the amp. FTC regulation to protect consumers is nice but not that essential. This is not medical instruments or equipment. One more thing that is important is the testing equipment, environment, testing personnel's qualification. Then, goes to the certification of the equipment, calibration of the equipment, the qualification of the calibration process. So, it could be complicated if you want to take legal actions. I would suggest that let the users to decide the final fate of the manufacturers. With today's internet feedback availability, consumers have the final say.

And we know those YTr's...CAM.

To remove the plate, all you had to do was remove the 4 screws on the edges of the back plate, the two screws below the passive radiator, and remove the volume button. The button, washer and nut. Once this was done, the entire plate would slide out along with the back cover.

Folks, Skunkie Designs is correct, stop buying Chinese junk, get real amps with real world ratings.

Great video. We have a mutual friend in the state senate. Call Jason and see if he can help.

Interesting and I agree with you totally. You know in the 50's audiences were assembled and told to listen to sound at various levels of distortion, the conclusion was that people couldn't detect distortion below 5%! fascinating.

Definitely file a complaint with the FTC. Government agencies are extremely responsive to individual complaints.

lol just saw your video put up on aiyima channel

I hate regulations. Unfortunately manufacturers in all areas are more than willing to decive the buyer. So here we are.

What is the correct stimulus for testing? Previously it was common to see swept sine tests but with the 5min requirement is a white noise stimulus more appropriate?

remember that bob carver crimson crap amp? officially 75WPC, bragged of 80-something WPC, had 15W edcor OPTs. when busted out, some were outraged, but not many of the folks who were conned by "bob carver."

Dang, I was gearing up for an anti-regulation rant. Wasn’t expecting to hear that the FTC did a good job.

Excellent report!

Thanks for your "much needed observation" (rant). Agreed 100%! Now, we can only hope for the enforcement of those regulations.

Will be interesting to see if the existance of a rule makes any difference to sellers lying about their products. Honestly I'd be happy if amplifiers with a metal chassis all had a ground connection. But then many of their mains leads don't even have a (working) ground pin on the plug 😅

Don’t forget the paid trolls 👿 Their all over the web

BUT how about power ratings for AVR equipment such as 5.1 or 7.2.4 etc? Is anything addressing the multichannel equipment

Steph taking the junk dealers to the woodshed. I love it!!! 😻

Fully support you on working on your own stuff. Not trying to fix others failures and junk. There is no end to that job, and you are right, that is not your job. I follow this channel for your own builds and creations, in addition to your reviews, attitude and general take on things. Keep up the good work and let the junk(es) sail in their own seas..

Can i ask you a question, wattage aside. What do you think of the Fosi Audio V3 mono amp? Of course it states more wattage than it is (with the included power brick). Do you think it really makes a difference in sound to have mono block amps in a cheap amp like this?

Output into 8 Ohms, 1% THD+N, 20-20kHz, 5 minutes. Lots of amplifier manufacturers are shaking in their boots!

That's awesome! At least I'll know what I'm getting in an amp that I'm buying. To be honest I always knew that the rating in the Chi-fi amps wasn't what it said it was. Now there's no wondering what they really are now. Thanks Skunkie! Your the master!

👍♥️🫂

I remember back in the 70’s when the power ratings and distortion were standardized but I did not know the FTC was behind it. One of the very few bureaucratic regulations that I approve of. Enjoy your break Be safe out there

Geez. This is sad. These products should be posted on a pinned post "wall of shame" for all audio enthusiasts to check.

I really hope they crack down on car audio . It's the worse. 1 company 3000 watt amp does 300 watts another company does 3000 watts and another company's 3000 watt amp does 9000 watts . It's just lies I don't care if you lie and it makes less and I don't care if you lie and it makes several times more . A lie is a lie and hurts the industry and makes it hard for newcomer who don't know better. Just stop the lie if it's 3 watts 300 watts or 3000 watts or 9000 watts just call it what it is . Writing a number on the box does not change what the amp is in the box
