Infineon MA12070 Class D

What about the difference between an unmodified BRZHiFi and the unmodified A8?!
BRZ don't have the bottom as A8 even with that expensive linear 19v trafo I bought to my Allo Volt+.
I run A8 with LRS-24-350 Mean Well at 23.8V...

I have switched between TPA3255 and A8 as LF and HF and TPA ofcourse have more bottom with 48v
but I prefer MA12070 it's right for my speakers and room.

Another edit:
With BRZ at top the 3D sound meets, didn't feel that with A8 at top with TPA3255.

I got two of this board today but it's version 1.5 without dip switches.
Those two resistors, R6, R9, measure 10k.
So if I want to run PBTL I have to move one of those nano bastards...

Sometimes I wish the designers of these things would think for a moment about how someone might want to use it in a way other than just as-is out of the box.

There's a capacitor on my HiFiBerry AMP2 I'd like to intercept, but they made it the size of all the other "bastards" and I dare not touch it, let alone hope to somehow get anything a little bit better in its place, without ruining the whole thing with just a glance from my soldering iron.

Thanks, whoever considered that particular cap as just another reference schematic BOM part placement on the board...

If you use 2 soldering tools you can lift the resistor. A bit like eating Chinese food with sticks western style :) The resistor will stick to one of either so quickly clean the tip to which it sticks to a wet sponge. Now take a stainless steel tweezers and solder it to the right place. If unsure that the resistor survived and/or still is reliable a new one can be soldered. Easy peasy. I notice a trend that resistors on cheap boards "loose" their metal end part at one side even after short heating so my habit is to place a new one.

The layout has improved except the possibility to solder 2 x 1 nF film caps after the output ferrite beads. This was easy on the previous versions.

Those look like small 0805 or 0603 size and small enough that a chisel tip soldering iron with a big wetted tip of solder will soften both ends and lift the part off with surface tension to the solder. Use tweezer to pull resistor off the board if that doesn’t happen after heating both ends with solder blob. Clean it off and solder back to other position one end at a time. Easy.

Is it a jumper (0R) or an actual value resistor? If a jumper replace with a piece of wire stub and solder. If actual value, measure first and buy some replacements. They cost maybe 2 cents each! Buy an assortment kit to have handy.

For example, very handy to have on hand for repairs, etc

"Easy". Well, if I routinely did the work X does, maybe I'd spend $400 on ebay for just the hot tweezer attachment for my Metcal station...

I've accepted I'm just too clumsy for 603 (1 mm...) SMD rework. I could always ask my wife; she's even 5 years out of practice. I can accidentally burn plastic bodied components and wire jackets working on point to point tube amp wiring! That's what's easy to do for me.
