I have no opinion to offer. The sound will likely be different. But would it be better?
I notice that the responses here are all sort of market-trading ones. Very Audiogon-y! No one has offered an opinion on your principal question which is what can you expect in SQ if you move from the VPI to the SME system. Since you say you are currently "very happy" with your vinyl SQ, that's an important consideration. If it were me, the only consideration.
One thing you might do is look for an old SME thread here or elsewhere and revive it. Since there are so many VPIs out there perhaps someone has already made a similar trip and would comment.
