Class D amplifiers. What's the future look like?

The modified Peachtree GaN 1 is incredible. 

+1

The non- modified Peachtree GaN 400 is a beautiful , lush, full sounding amp that is smooth and detailed at  same time....BUT....use a Tube Preamp....Thinking about Ric Shultz's modding this amp but it's soooo sweet as it is..When you win the Lottery, get an Aavik with the Pascal module.....That's another world.

Dropping back and punting. Just the basics. Why is there this "push" to Class-D in the first place? What do you gain? In what way would they ever be sonically better than a good Class A or AB amp?

I love new technology as well as the next guy. But other than offering good "slam" in a powered subwoofer (and the limited frequency range needed in one) why is there this "push"?

Is someone going to tell me that say 5 years from now, you’ll be able to buy a $1000 Class-D amp that sounds BETTER than a $4000 Class AB amp or a $4000 tube amp?

I mean, where are we going with this? And why?

And no, it isn't about "saving the planet". The amount of electricity used by all audiophiles is paltry compared to that used by far more mundane tasks such as drying your hair in the morning with a blow dryer. Those things are 1500 watts - continuous.

@moonwatcher Because it keeps getting better and better especially with the latest GaN and Purify amps that are being compared very favorably to top solid state and even tube amps.  When Ralph at Atmasphere not only designs a GaN amp but chooses to use it in his own system over his very highly-regarded OTL tube amps and that avoids all the expense and heat of tubes in a much lighter and more compact design it’s hard to deny the technology’s merit and future potential.  Plus, at least in the case of the Atmasphere and AGD amps, they’re upgradeable as the technology continues to improve.  The times they are a changin’ and ignore it at your own risk. 

@soix thanks. I'm glad it is improving if this is the "future" of what sonics we will have. I'm 65 and likely won't have to worry about it, but I hope it will get better and better - at least as good as the best Class AB amps are, and if the transfer function can be attained that gives them a touch of "tubiness", then all the better. 

I'd hope that 10 to 25 years from now, audiophiles will have access to great sound using these continually improved Class-D amps. That is after all why we all got into this, regardless of what technology we use to get there.  Figure Class A, Class AB solid state, and SET or push-pull tube amps will be around for a long time, just because there will be some who will want them. 

Love the idea that you can upgrade the amp along the way with better modules without having to trash it, sort of like Schiit does with their Bitfrost 2/64 DAC.
