I've read a lot of your responses and I wish I had the fundamental understanding about Class D that you have. I have a PhD in physics but that does not help me understand these little amps when I patiently solder them up. But I still enjoy the posts from people who know more than I.
The only thing that I know is that there is something very special happening here. If these cheap amps can receive so much attention, even from major audio journals - and have millions of ears who say WOW - we need to figure out why.
I would suggest that if that is simply from the addition of a high class cap - some experts need to divert their attention to electrons in caps.
I'm listenting to three off the shelf Class D - unmodified. Charlize, Amp 6 and DA-10. Unfortunately (?) I am listening to them in preference to the $50.000 of high fidelity gear upstairs - don't tell my wife that.
Food for thought - but don't split the forum

Class D is in fashion now (and it is for commercial reasons). Fashion is far more powerful than science when it comes to motivate people.
The only full range class-D stuff that I have listened to are my own circuits, and they have their drawbacks, but what I enjoy of them is the particular way in which energy is handled. Note that I also enjoy horn loaded speakers for the very same reason (these are devices that transfer 10 times more amplifier power to the air than direct radiators).
What creates fashion - a few people with their own individual "good" taste stray from the norm - and start something.
I thought that Class D chips were originally designed for high efficiency (small size) applications like automotive or mp3 players -and then some fashion oriented people decide they liked the sound better than their sexy high end audio gear?
I guess that I want to ensure that this wonderful stream of experience in audio keeps coming so that I can enjoy it
I think it's a good idea just to split between existing product tweaks and design yourself issues, however they may be titled.
My amps are powered up almost 24 hours, and sure would like the effeciency of class D with good sound.
I beleive this is the result of focusing the power.

Hi Eva,
People, there is nothing different happening here than in solid state or tubes or chip amps. Your power to ignore a thread is as easy as Eva stated. I don't like the idea of offering up a complete, optimized design in any forum. The design should work, but can be taken further.
Look at the Symasym threads. Mike and Pavel have done a wonderful service to all, but look. More people are becoming involved and taking it further. That's DIY and that's co-operation. The same occurs with tube projects and everything else.
For some members, a kit may be all they have time for. I feel that's fine too. So let them buy the board, or kit. At least they are soldering something together. That's a far cry from buying a completed commercial amp. If they then want to find out some more, let them. You can always ignore whom ever you want to ignore.
That's my take on it. We sure as heck don't need any more splitting and sub divisions. That's a personal statement. The other moderators may have different views than mine.

Sadly, yes. Nice to see you again BTW.

If splitting means the possibility of more work then I don't think you'll find any arguments on this side Chris. 😉

I think this is my 1st post in Class D since it doesn't interest me....BUT I had to share my opinion: STOP splitting the forums! IMHO, it's only made things worse. When I was a newbie, I spent 95% of my time in the Loudspeaker forum. Now, I can't stand it anymore, because so many of the savvier people moved to the Fullrange forum. Argh! 🙂
OK, we mods discussed this. We considered how much complexity we wanted on each forum and the number of hierarchies which people can deal with. Also how a lot of catagories segregates members to a greater extent, balanced by how more catagories give more structure and maybe less confusion.
We discussed how technical issues, and building issues are often intermingled so its hard to separate them. We discussed how we need to work with newbies and how interesting ideas turn up in those situatons sometimes. We also looked at how other areas, such as Loudspeakers, work.
From the varied posts here it is clear that there isn't a simple answer, but the mods participating were unanimous that adding another catagory isn't what we want to do.
The problem initially mentioned could be addressed by starting one or more technical threads, and reporting off topic posts to keep them focused.
Thank You,
Variac
I have to agree with the mods on this one. Why should they have to do more work because of the few who just can't stand to see another thread like "is this cap any good" or "will this power supply work with my T-amp".
There are redundant questions like those on every category of this wonderful forum; your not obligated to click on any of them.😉
I think people on both sides of this matter need to put more effort into what their looking for. If your looking for technical information you can either scroll through current threads or use the search function. If you want to know "is this cap any good" or "will this power supply work with my T-amp", then you need to also scroll through current threads or use the search function before you post.

I'm sad to her that the mods don't support a split. I've thought about another option though. Would it be possible to add a filter to the forum, so I can sort out the assembly threads (like a spam filer)? Right now there's pages between the interesting design threads with people like Bruno or analogspiceman etc. and it's only getting worse.
We had a PhD course back in August here at DTU* with participants from other universities and the industry. There where several users from this forum, but sadly some of them had stopped using it. The reason is that quality of the threads has dropped and the forum is floated with threads that has no content. I haven't been active here for a long time for the same reason. I think that if you don't do something and just ignore this problem, the newbies will take over more or less completely.

Hi sovadk,
What would you have us do? The same thing occurs in every single forum on this site, except that this is the only forum complaining about it.
Have a look at the title, possibly the first post. Decide then if you wish to read more. It isn't that much of a hardship - really!
The best thing that we have offered to our members is to clean a technical thread if requested (and the request is valid). This means more work for us, but we are willing to try this. An exclusive club is one that dies out with out new members. Where do they come from? Well, they learn somewhere. You may as well have a hand in directing their course rather than have to battle them later.

Hi Kaspar,
Thanks for taking the time to comment. Please be aware that we are doing our best to enhance everyone's experience here. So ideas and constructive comments are more than welcome.
Understand too that every thread will only bring to "you" what is put into it. By you, I mean all members. I'd like to see new members respect more experienced members by searching and posting new or posting intelligently on topic. The more experienced people will be responsible for the tone of the forum. It would be nice if they could take turns helping people learn a bit when they have time. The best way to learn is by teaching someone else.
The day to day existance of the moderating team is a janitorial service. We are members first and would like to enjoy this place with everyone else. Knowing the moderators, I can't think of one who is anything but a caring member.

One can create their own "spam filter", by only subscribing to threads they want to read. They can also choose to filter out any member they find annoying. Extra work for the mods was never mentioned as a consideration in our discussions.
Since we have this thread open. I've been wondering: This forum seams to be most active in the weekdays. Are most of you employees sitting at your work space when you attend this forum?
If I was able to at work, I would 😀
Unfortunatly I'm way to busy, and only have the time for class-d in the evening and in the weekends, and that is in tough competition with my family 😉
Class-d is just so unbelievable time consuming (for me at least) 🙁 ....... think I should that a weeks vacation just to finish (work on) some of my D projects😉
