Well...if you believe Jonathan Valin it's either the AC or the Walker Proscenium for budget priced musical nirvana. :)
I'm not running an AC but a Raven One and, echoing Halcro, it's important to optimise a turntable until it either reaches its full potential or matches your expectations e.g. by choice of mat, table, shelf, tonearm etc.
I don't use a shelf but a progressively decoupled 3-tier tripod table (2" thick laminated oak shelves) mounted on a solid concrete floor.
