I found the finger lift on the Sumiko when mounted with the cartridge and headshell causes quite a bit of distortion.Most of the finest tonearms utilize finger lifts:

Hadcock, Triplanar, Graham, among others.
The finger lift on my ZuPreme causes absolutely no distortion that can be detected with it on versus with it removed, or in comparison with the stock Technics headshell.
I'd focus on proper set-up of the cartridge, arm, and leveling the table along the arc of the stylus.
