Quick check of my collection shows 6 Dvorak 9th symphonies, I have owned a few more over the years but have not kept them.
Here is my list and my favorite:
Davis/Phillips Duo (7,8,9 sym)
Kertesz/Decca
Kondrashin/Decca
Dohnanyi/Decca
Neumann/Supraphon
Kubelik/DG Double (7,8,9 sym) or DG Originals (8,9 sym)
This is my top choice overall, available in many combinations at reduced price. Also DG has complete set of Dvorak symphonies with Kubelik at budget price.
Fischer does not have a lot of recordings out, I have heard of him but have no CDs with him.
