Next Gen of Victor A950

Like the title said. Which model are the successor of A950?
Found few A950 online but im afraid its an old stock which the rubber might get hardened abit.
Plus half side of me just want new design:p.

Browsing on their website, i saw A920, A922, A830. Just cant understand their numbering. Up & down. Higher are better or each number had their own meaning.

Like the A830 design especially the black/white one. But is it downgrade or not?
