Sound Tweak Rpi4

I probably understated the improvement with MPD 0.22. It's massive. I've also been listening with the Linux Audio Adjustments added to MPD 0.22, and it's very similar to too much feedback in an amplifier. Less distortion, but the soundstage is severely reduced and overly compressed. I think it could use a bit more of the feedback effect (whatever might be responsible), but it's better without it for most music. It would be very beneficial if there were a way to dial in that effect, like you can with feedback. Another possibility is that one or more audio amplifiers in the chain have too much feedback, and reducing distortion in the DAC process exposes it.
