I could not agree more on Basis. I moved from a Rega P-25 to an older Basis 2000 with a Basis modified Rega arm. It was far superior to my Rega table.
Recently I bought a Basis Vector 3 arm and replaced the Rega arm. The difference, to quote my wife who usually does not notice this sort of thing, said "Whatever you changed made more difference than anything you have done before."
