..just adding that now my curiosity has been aroused
I located 2 different lower medium quality coded mp3 downloads of "Noah's Ark Trap"
and they are dramaticly different in tone quality.

One is bass heavy and boomy, the other light and airy with hardly any bottom end.

There are just so many technical & equipment factors to consider
accounting for these extreme tonal differences.

Though, I do remember being a teenage HiFi buff back in the 70's
and how much pot luck determined
the sound quality of any brand new vinyl LP pressing.

BTW, to what extent were the Leader recordings sold as cassettes or even consumer reel to reel tape versions ?

That might offer another option for reasonable quality transfers to CD.
