If you were to use them without a side by side comparison in a very good system you would not be able to tell the sonic difference. If you replaced it you would not "notice" the change once you acclimated to it within a very short period of time.
If you changed to a different brand/geometry and construction, this would have far more effect than the additional 2m or so.
