Looks like you don't know what a R-C phase shift network do...
http://www.learnabout-electronics.org/Oscillators/osc31.php
And you're still failing at understanding the fundamental difference between a resistive load and a reactive one and how you can't just apply an R-C filter to obtain a phase shift when you have a resistive load.
Since I'm talking to, as you stated yourself, an "hardware developer" (which means absolutely nothing unless you're more specific, you could be someone who designed washing machines, telescopes, or boats, but whatever), I'm taking for granted you know how passive networks work, so I shouldn't be here explaining the differences between a resistive load and a reactive one.

Prove it!You Just talk, you don't back up anything you say with any evidence.
QSound is a proprietary encoding system and as such there's no documentation and I can't prove anything, like you're trying to do. I only make educated assumptions based on my knowledge of how electronics work and digital audio encoding and decoding.
When I'll get my hands on a QSound amp, I can make a comparison, but of course you might want to refute that due to being a very "unscientific" way of proving my point.
The only thing we have is the board and, honestly, looking at the circuit is more than enough for me to get to the conclusion that it is nothing more or less than a common power amp.
To
DECODE QSound you need a matrix
DECODER, that it's the problem with you, you don't even know what a matrix decoder is!
https://en.wikipedia.org/wiki/Matrix_decoder
A matrix decoder doesn't have absolutely anything to do with QSound. Actually, if you *really* want to stretch the definition of what a matrix decoder does, you might say that QSound was an alternative to the traditional matrix decoding, created to give you a 3D effect without using extra hardware.
Since you're speaking of matrix decoders, you should be familiar with one of the most famous and used one which is Dolby Pro Logic which was initially used to encode 4 discreet channels of audio to 2 and then, through a dedicated processor can get the original 4 channels back. Notice how it didn't achieve this through a network of caps and resistors, but a custom processor dedicated to the decoding of the signal.
There are no pre-recording or encodings with QSound in CPS2 games.

Prove it!
You know what, forget it.
You don't understand how a matrix decoder works and want to come here to "debunk some myths" with no evidence?
If you say people don't need that Capcom amplifier to decode QSound YOU HAVE TO PROVE IT! Show us some evidence, them people might start to believe you.
Since you speak with such an attitude about QSound, which, again, it's a proprietary system, I can only guess that as an "hardware developer" you were part of the team that developed it?
If so, then please speak up and let us know exactly how it was developed and please accept my apologies.
Otherwise, if I were you, I'd just follow your own advice and forget about this and let the people judge by themselves.
