I'm afraid it sounds as 44 to me.
Do I need to (I thing you call it) dither it down to 16bits as well or is it OK to have a wavepack 24/44khz or even an AAC 24/320kbps? Does it make any sense?
And I actually have no clue how much a pop/crackle can go above the "peak of the music" ... anyone?
Do you thing these are optimal settings? I was looking for information about aliasing/imaging and dither but looks like that's too complicated to me. Do I need it when I convert my records?
TPDF dither or low noise shaped dither like low-shibata or modified-e-weighted (or eventually foobars internal dither if you do not use SoX command line) is recommended for converting to 16 bit.
