Dear god I am an idiot. I'll have to redo the review of the 4CH module because it does indeed have two chips in BTL, not one in SE...

The board I measured is a single chip design with 4xSE outputs. See section 10.2.1.2.4 of the datasheet for details on using a master...

my read of this is that you are free to build your own set for private home use but if you use the plans and sell them to the reds or...

No, this is not correct! It is for choosing between single ended and differential input signals. BTL or SE operation of the output...

It doesn’t have a “sound”, unless you use it with a very high impedance tweeter and have exceptional hearing. Remember that with these...

Cool vid! Having been to a few factories over there, bigger and smaller, this definitely looks high-end / boutique to me. It's unusual...

The graphs are with it off. The amplifiers gain is reduced by the amount of feedback used, but total power will depend on the input...

High efficiency high power amps are super cheap these days. When a stereo 250Wpc amp is $300, is speaker sensitivity a big deal? Seems...

I'm not going to argue with TI, it's their chip :-). However in practice this isn't an issue for complete amps or amps using typical...

For full disclosure: From here: https://www.ti.com/lit/pdf/slaa787 I don't see any mention to radio stations whatsoever, only to...

Sharing power supplies is irrelevant to that though. The linkage is between the clocks in the amp chips. In principle clock drift...

That… doesn’t make much sense? The power supplies are DC

Unless you have an AM radio in the same cabinet it’s irrelevant. I have 4 modules in a diy amp without using the clock slaving and it’s...

Not true, it’s a great device! I just think since you need an 800W PSU it’s going to have to be internal, and it’s going to have inrush...

Of course they do, but I seriously doubt it would make a measurable difference if they were shared in this application.
