This is like increasing the gain on an aftermarket amp - it will sound louder
while giving the impression that it is a "better" sound.
The reason that the Dynavin apparently sounds better than the OEM HU with HiFi low
level outputs into the OEM amp is due to the Dynavin high
level outputs into the OEM amp. It has nothing to do with having a better signal, just a much higher amplitude signal and current input.
If anything a low level signal is relatively cleaner
than a high level signal by definition, as a low level signal is pre-amp.
The good news about this is that somehow the OEM amp can accept high level signals, but the bad news is that we do not know how much of that signal power
it can accept and for how long before its input stage is burned out. So this is a crap shoot.
