Does it make sense to upgrade ML 31 to 31.5?

I own a Mark Levinson 31 CD transport. I am thinking about upgrading it to 31.5 status, but I was wondering if it will really make any significant difference. Has anyone done this, and, if so, could you comment on the results?

Thanks in advance.
Depends on the gear behind it - that goes a long way in determining "significant difference".
Oh yeah. The gear behind it is: Cello Grandmasters, Cello Performance Amps, ML 360S, DCS Purcell/Delius. All running now through Krell HTS 7.1 mk3.
