Class D amps seem poised to take over. Then what?

I am certainly biased by my lifetime final amp being a Class D. But I know that after 30+ years of development, Class D seems to be on a high plain. I know there are now many, many companies focusing on Class D and, maybe, a good handful already as good as it gets. My Class D amp is as smooth and beautifully musical as a great tube amp and as punchy and detailed as a great SS amp. I am satisfied and done with my search. A class D amp has effectively taken me off the amp merry-go-round. It’s about time after 50 years. And, for me, this Class D is a milestone. Will all other classes of amps fade away?

WOW! You know what my system sounds like yet you have never heard it.

Now your a mind reader knowing what i will say next. Bravo!

I was in the industry for many decades, building and designing, amps, pre amps and speakers so it's easy for me to tell who's winging it and those who know their stuff, keep winging it george i know better.

@georgehifi - to be clear here, I saw the post after mine (above this) and I wasn't be combative, I was giving you the benefit of the doubt.

I know a bit more than Ohms laws, so I have genuine interest as to the limitations. Which there very well may be.

@georgehifi - wouldn’t it depend on the original rating at 8ohms, the power supply rating that feeds the class D modules?

No, although it to needs to be beefy, look at any Class-D that has been independently wattage tested into 8ohm 4ohm 2ohm regardless of powersupplies (most won’t get test into 2ohms), they are fets, and fets can’t do doubling of 8 to 4 to 2ohms (current) like complimentary bi-polars (bjt) can do like in the the Gryphon Antillion, bigger Krell, D’Agostino Boulder, etc etc etc

Also look at my post in the  "Pass X260.8 vs Bryston 7B3" thread

Cheers George

Would you agree that the actual GANfet used in AGD amps is proprietary? The comparison has been made to Nelson Pass acquiring all available SITs. Although Nelson does not hold the patent on SITs as does Alberto on the AGD’s GANfet.
One reason I bought AGD is because I was convinced that they stood apart from all other Class D.
That all the others used variations of existing technology (chips).

earlflynn, thanks for the response. I totally understand passion,and brand loyalty.  I'm a motorcycle enthusiast. I ride Victory bikes. I was also in an MC where everyone else in the club rode HD. While we used to bust each other's stones, it never got to the point of hostility.  I guess when you can only see written words,sometimes what is meant to be passion,comes off as pompous.
