What products you'd like to see WiiM produce?

(*) Have you ever soldered your way through an amp? Done schematics for it? I have.

I believe @harkpabst is an EE by profession, so I guess he’s done quite a bit of that. And more…

Sorry man, it's PURE ENGINEERING (*) and simple electronics and EM.

What is EM?

 

[TonyE]

And I do EE as well... and computer engineering too. Professional background in physics.

So there.

Heck, I just had to bias a big Class A amp the other day... used brand new clip that had some oil in them.... SMOKE!

This particular one was done with dual Meanwell switching power supplies. A very unusual DIY amp.

What is EM?

Electro Magnetism.

In Physics, electronics fall under EM.

It’s like Thor versus Hulk in here

Perthaps, I should have used the term "Dynamic Range" as opposed to Peak vs RMS... since that implies the square root of 2.

Google "dynamic range of an NAD amplifier"

• Dynamic Headroom/Power: The ability to handle musical peaks (10 to 20 dB above average) by providing short-term bursts of power, such as the NAD 2200, which can deliver 400-800 watts.

Google "do smps power supplies have high dynamic range"

In my DIY F5m amp, we went with dual rail Meanwell 24V, 211W (709-LRS-200N2-24) power supplies even though the rated output for the design is 25wpc (class A). I also have a "classic" F5 amp with linear power supplies and big capacitor banks and a huge toroidal. Guess which one sounds more "dynamic"...

Not only that, but my back appreciates the change every time I pick up the amp.

So how do you get this higher peak power without a much higher power supply voltage? 6dB increase in power would need double the voltage.

It's not just about how much you talk. It's also a matter of grasping the context. And keeping physical facts straight.
