Cheap TPA3118D2 boards, modding them and everything that comes with it

You're right. It is attractively efficient. And it isn't terrible.

Must be the language barrier but your posts are hard to understand. It is better to use clear language instead of gibberish speak certainly on an international forum about technical stuff. Maybe posting a picture here and there would help in such cases. Please read your own post #737 and try to decipher the information...

Example:

"That girl is attractively clothed. She isn't terrible"......

Not much valid info, many ways to understand. No real data. Could be a butt ugly but well mannered girl in bikini.

Right on. That's the case. It is wonderfully efficient and doesn't sound terrible. I will be trying it again for my battery powered application.
It might need a baxandall to reduce the tirade.
Efficiency also means low power supply costs. So for us that don't wish to spend a lot and still get good and somehow loud sound, I don't think there are many other options?
Efficiency versus Enjoyment would make a marvelous spreadsheet indeed!

As for me, I'd saved approximately $4 per channel. Cost of a tone problem, about $7 versus a slightly less efficient amplifier with thermal management costs of $3. Same power supply did either just fine. Relevant output is cheaper!

It seems you speak a different language which is then translated. Am I right you speak french originally ? Your posts are very hard to understand. We can not read your thoughts so please write in clear sentences and group answers to the right item instead of cross linking to previous posts (without mentioning that). In short: your posts seem like answers to your own thoughts.

Perhaps Daniel is just giving you guys who deliberately try to confuse we, (the less knowledgeable), with murky abbreviations, lots of numbers, and insider references.

I have been advocating clearly constructed sentences, accurately spelled words, and understandable posts on this and other forums. But, I'm basically told to just get with it and catch up.

I hate to burst certain bubbles...but not everything is quantifiable.

Sorry but you entirely miss the point. Point me to people who are "deliberately confusing" others. BTW it is "us" instead of "we" in your language.

Those murky abbreviations, lots of numbers, and insider references is what everybody has to deal with when using the manufacturers datasheets and forum. Add the necessary basic electronic knowledge and some experience to that. Chips are not described with colorful language but with dry numbers, drawings and graphics. It can be confusing at times but you get accustomed to it after some years. It is like this in many technical disciplines. For example I am working in a field where "techno babble" or "jargon" is mandatory even if the guys themselves dislike it.

However, many try to abbreviate even the most basic answers which indeed does make things cloudy. IMO this due to the "smart phone phenomenon". How can I say something with only 3 words 😉 It would not be the first time I send a PM to members in the thread to elaborate matters by means of PM.

Communication my friends, is THE most difficult matter regardless what you do or where you are on the planet.

May I suggest to go back to the subject and have a mod weeding out irrelevant posts (including mine) ?

Second suggestion is to adapt to the level of beginners which does not hurt anyone (except stepping down from the guru chair for some 😉) and use plain and simple language. It just costs some extra typing. Please no references or hidden references to previous posts. For example when gain is described let's just mention the right resistor numbers for that specific board with the gain factor with it. Like that, if that is clear enough for you. Also let's avoid bringing other boards with other chips in the thread.

Agreed ?

I don't mind people occasionally bringing other boards with other chips into the thread, on the proviso that other boards with other chips do not become dominant

Had someone not done that, I may have missed something worth trying, eg: the Sanwu TPA3118 was originally posted on the 3116 thread; had it not been, I would probably not tried the 3118 as soon as I did .... the physical size of the Sanwu makes it vey useful, as far as I'm concerned

Apologies

Sorry that I had done an incomplete job:
I tried only one sample (one board), didn't explore if there were frequency settings (that might be different), didn't check that energy-saver setting (in the datasheet), didn't try adding series resistors to the inputs (for reducing cross currents), didn't try more complete input filtering, and didn't try anything with the output filters.

So, it is probable, that the performance shortfall that I experienced was caused by a lack of effort on my part.

However, I would like a board with bigger size parts that would make exploring it more doable.

Just to clarify:

3116 and 3118 are the same except the location and thermal impedance of the thermal pad...one on top one on the bottom.
