Can we get a Class D Amplifier Category like we have for Tube And Solid State?

I haven't made up my mind about anything. I might hate it and send it back. Of course I will post my impressions. If my opinion influences people or doesn't, whatever. But I have turned others on to some equipment that they love. This is all subjective though and what I might like you might not. We are just here to share opinions and experiences. But as you, I too reserve judgement on the sound until I hear it myself.

But I do have high expectations on this amp.

Your thread about this amplifier in New Gear- Performance is why I said you've already made up your mind.
 
Solid State is the right forum for class D, I agree. Don't engage nay-sayers, and the thread won't derail. Grow thicker skin. Member X doesn't like class d. So what? It isn't my first choice, either. But again, so what?

Some folks love Klipsch, some hate. Bose, same thing. Along with other brands, or even eras. Opinions will differ. Some folks can't disagree without being disagreeable with their remarks. Ignore them, and it becomes one registered nay vote. Arguing is what derails a thread. Debate is one thing; recognizing the difference between debate and senseless argument quite another.

I don't agree that we need separate forums for each SS class., nor that we need single one out for its own.

All very good points. But there are some on this forum that I actually trust their experience and opinions. And I come here seeking advice on Audio equipment because I sure don’t know it all. I have had a ton of experience myself and especially the past 5 years. I have gone through so many different speakers and amps and DACs and so on that I have really fine tuned and have figured out what I like and what sounds good to me and what works and doesn’t. So believe me, I am not going to let the negativity of a few away my decisions.

And now that I know Class D is pretty much considered SS, I will post all Class D amp stuff there. I was just confused. Lol :)

You are just on a different HiFi journey to me and that's fine. Clearly burning through lots of speakers, DACs and amps trying to find what you like, is 5 years of enjoyable fun and experience. I'm happy for you. We've all been there at one stage.

I'm at the other end. I trust nothing but measured performance by either a trusted technical reviewer or fully tested on my bench before it even gets a chance to be listened to. Then I let my made-of-meat ears decide what I think.

Just out of interest, has anyone actually properly bench tested this cherry amp?

SS (solid state) vs tube (or valve) has nothing to do with whether an amplifier is Class D, A, AB, T, H, etc. SS simply means a device that doesn't use tubes, and many tube amplifiers have some solid state devices in them.

You could, in theory, have a Class D tube amplifier but I don't think anyone currently makes one (and there'd be no audio advantage to doing so), so any Class D amplifier you encounter will almost certainly be solid state.

Oops, I should point out that unlike the others, "Class T" isn't actually a circuit topology, but a marketing trademark for a Class D amplifier made by Tripath.

Here's a good topic for another thread, all the different company "classes" used over the last 40 years. "The New Class AA" Technics, "Super A" JVC, Wasn't Class H Soundcraftmen's favorite?

I'm surprised nobody used "Class A+" as a marketing gimmick. It could have been proudly written on the front panel with red marker.

This raises the question of hybrids: put them in SS or Tubes? I have 2 hybrid power amps now, other in the past.

If the output section's tubes... Tube. If the output section's SS... SS. If the output section is neither tube or SS...?

No. I call out the blatantly misleading, deceptive and incomplete specifications used by many Class D 'manufacturers'.

It appears to me that class D is now mainstream. All of the better Pioneer receivers are Ds. Units like the attached Pioneer perform just fine. I doubt that they are using deceptive specs. At any rate, the distortion is below the human hearing range, so many are considering the advantages of weight, size and heat production. Of course the attached would only have the heat advantage..My guess is that class D will be the standard in even the very expensive amps within a few years due to cheaper cost of production and the fact that the younger generation doesn't want a bunch of large boxes sitting around

This is a sign! The amplifier Apocalypse is coming! Properly adjust your quiescent current before it's too late!

They want a portable amplifier accessory with app for their phone.

"Now you can plug your phone directly into speakers! 200 W of awesome power for rockin' the house. App sound settings include: 60's Tube, 70's Receiver, 80's High-end separates and 90's Honda Civic with $10,000 of car stereo crap!

As an owner of both a Ncore amp and a Benchmark AHB2 feedforward/feedback/current dumping/supply switching amp I feel that the Benchmark and THX amps are being discriminated against and I demand that they have their own section if there's a class D section.:)

...And their own private access ramp, special facilities including speakers of their choice, along with a unique 'Class D' ID card that gives special deals and group-buy discounts at all participating HiFi dealers across the US. :)
 
Class D amps are not any more special than other solid state designs...regardless of their current popularity.

It would be like adding a "3 way speaker" sub forum in the speaker forum.

Well, they are a little bit special- there are so many aspects of their design that is different from other SS amps. From a circuit topology/circuit theory perspective tube amps are closer to class A/AB etc SS amps than class D amps are.
 
It seems to fit under "new gear - values" as class d usually has those attributes. My class d ( TPA 3116 ) thread there has over a million views. That's huge traffic for AK. There's no denying the interest.

Seems like it'd be simple enough to add the same tag feature to any forum similar to what you see in barter town. Add those to a thread and they show up in the post lists as well.
