FTC may end amplifier rule! ACTION NEEDED

@russ69 yes. Class AB is the boss but it has hit a ceiling I feel. Innovation is harder to come by in class AB. Mind you I currently run a 5 channel parasound in my HT and love it. On the other hand class D has room to grow. I can say the NAD amp I referenced was cool to the touch but capable of reference levels with a very clean and neutral presentation. I would up returning it because it was almost too neutral and a little dry for my tastes. 

@itsjustme  - I agree with you 100% that the current regulations aren't particularly relevant for the kind of amps that most audiogon contributors would care about. But these regulations were originally developed for less sophisticated customers and are probably still somewhat relevant for the class of product that would be sold at Best Buy or Walmart. 

I think the most valuable part of the regulations were to come up with a standard definition of measuring power. But I agree that it makes more sense to talk about sustained RMS power and peak RMS power (maybe 5 or 10% duty cycle) separately, and perhaps also peak RMS power into a more reactive, lower impedance load. 

But I think that most more-sophisticated customers are going to do the research to understand if the amp is going to work with their particular speakers, room, and listening preferences, and are going to pay less attention to the FTC-approved ratings.

This is a fair question and I'm not trying to stir any pots... but do you think the future is well made class D amps?

I think we are currently in the time of well made, good sounding class D amplifiers.

I think we have to realize that music lovers don't necessarily want a big room with 1/3rd of their floor space taken up by big gear.  Lots of music lovers are looking for small and simple.  It's now the early part of the 21st century and there are getting to be some great examples of this.

Take a look at the Anthem STR integrateds and HT receivers for instance. I don't own one, but imagine it.  Class D, built in bass management, DSP, Streaming, DAC all in one.

What is my real justification for having right now:

• Streamer
• DAC
• Integrated

I mean, to stay with separates, and stay with linear I have to really really love the sound.  Class D, along with full functional integrateds or receivers are the bulk of equipment sales to music lovers.

What will I personally do?  I am not sure.  I'll have to wait and see after my new room gets fully set up.  Perhaps I'll begin auditioning gear in earnest to see how well a full function integrated with Class D can do.

I was fully Class D in the past.  It was the equal of my previous A/B amps.  However my current A/B amp beats that, and I don't want to give that up.

I think the current rules are too lax. The consumer deserves a truth in advertising code that actually helps with purchase of an amp for a given loudspeaker.

@jaytor yes I think the hard-core audiophiles will be just fine but the fledgling and intermediate audiophiles will be lost trying to figure out what amp is best for them when the listed specs do not match with what they can actually get out of their system and what they think they purchased. Imagine the confusion of trying to select the best amp, which is difficult enough as it is, when the specs you are seeing are not even close to truth.

@itsjustme I agree. Part of this call to action is that we can request and demand amendments to the policy. Ie gene has suggested that multi channel amps list their power ratings based on 3 channels driven. I do think peak contious power is important given the transients that come up in both music and HT.

@unsound yes! Please comment in the link I posted. Hopefully it will make a difference in keeping the rule alive.

@erik_squires thank you for your candor. Most audiophiles in this forum are all about what’s "best". The truth is we are all trying to make it work within our environments and our budgets. A retiree who saves up has a chance of spending whatever they want on their system. A go getter who’s trying to make it might be living in an apartment with a tiny listening area. Not suggesting you are one or the other but the point is we are all audiophiles striving for a great sounding system. That is the definition of audiophile. There are no right or wrong answers. I’m not saying specs are the end all... but they are a great start to inform consumers what they are purchasing.
