Linn LP12 vs. VPI Classic 1 and 3

As an owner of an LP12, I am considering an upgrade to a VPI Classic 1 or 3 or 4. I have heard a Classic 1, but not in my system. Have not heard the up scale Classic 3 or 4. So my question is- for those who have heard or own the Linn and have heard the VPI's, do they sound better than the regular Linn Lp12 with Valhalla ( my version),...can they and do they beat the Linn with Lingo, and do they compete with the uber Linn-LP12 Radikal/Keel? If so, which models of the VPI are the winners in these comparisons ( if that is the case at all).
