FTC regulation test for amplifier is current hot topic. I would genuinely like to read if any Modern Class AB commercial amplifiers like Marantz, Cambridge Audio, Denon, Pioneer or Yamaha has been tested with these regulations. so please share (Link, Website, etc).

1) How much power it delivers is not important
2) Misleading ad for power is not important
3) No vintage class ab amplifiers of golden era
4) No DIY amplifier
5) No Pro amplifiers

Aim is to just to read about if any modern class ab amplifiers pass this test or at which point it self protected itself.

Thanks and regards.
 
I haven't seen any yet. I tried asking perplexity with no concrete results. I believe we are in a transitional phase..
 
Marantz pm6007 and some Yamaha are very popular here (India). If any ftc measurements even if giving 50-60w/8ohm and 80-100w/4ohms I may consider buying. But nonetheless knowing any measurements even if not buying will be good to know, learn and compare.
regds.
 
What made it a version? One hopes it's not an interpretation of what five minutes means?! ;)
I asked this in one of the threads on the FTC rule. Amir explained how the test was ran with the AP which doesn't seem to meet the exact letter of the regulation, hence the word version.

Looks like Yamaha mentioned above is good amplifier. Nord amplifier also passed the same test it seems. sweep vs. individual channels test for 5 mins. should be made clear.

When the term "continuous" can be interpreted to encompass such a broad spectrum of durations -ranging from as brief as 2-4 seconds to as extensive as 5 minutes or even indefinitely -it naturally raises questions about the consistency and accuracy of these definitions. With that in mind, it seems entirely reasonable to also scrutinize and perhaps challenge the very definition of "five minutes" within this context.
