... compared to Z3TA+2 the sound quality of the original Z3TA+ is really not great
That was one line they marketed Z3TA 2 with, when it came out. It is absolutely not true!
I opened presets from the z3ta Classic installation sound bank in both versions. They sound absolutely the same.
I also designed couple of new presets from scratch in both synths using the same "recipe" and again, same sound.
