The ability of any tonearm to "outperform" another is largely based on 2 factors:
1. The cartridge(s) used. It's difficult to assess either the tonearm or cartridge performance without considering the other. There are very good and very bad tonearm/cartridge pairings. It's critical to match properly.
2. The skill of the user as it pertains to installing and aligning the tonearm/cartridge.
I have the opportunity to install, set up, and tweak many turntables; quite often the owner has, in some way, not optimized the alignment.
