I think that with your latest settings you're on to something.
I tried the SBT priorities + TT3.0 + Buffer 2 and my first
impression is that the music is presented more naturally; the flow is
more effortless; there is greater detail, but without losing
to explain why you didn't like the balanced, detailed,
engrossing sound.
I don't have to tune my system for any other source, so the probability
is the issue lay with SBT and TT3.0 and so it proved.

4. the advantage of the SBGK p62 settings is that there is headroom to
play with from jivealsa at 45 all the way to 75 and loadavg from 50 to
76. I you like TT3.0 sound you can just change

we have no control over. so changing priorities away from the base
