If VTL offers use original part, if for no other reason than resale and appearance.
Barring that, the two aftermarket binding posts that I've installed and like very much are the Cardas (with and without plating) and Vampire.
Be sure you measure original posts overall length before you order any aftermarket version. Some aftermarket versions are very long to accommodate a thick chassis or a speaker cabinet.
I have not taken apart a VTL 450 but suspect the originals are quite short.
Let us know how you do with this.
