I am quite familiar with all those tables, including the B&O RX2. I will say that although the B&O is a nice little table for the money, all the others you mentioned will be a step up from the B&O.
I'd say that you will hear an improvement through your Adcom, or just about anything else you might play it through.
Another table you might consider at the under $1k price point could be the Nottingham Horizon.
If you are willing to consider a used table, then you can have even a larger number of choices. A good used Linn LP12, Sota Sapphire, or Well Tempered can be had under $1k if you look around.
Check in with Jay at Audio Revelation, an Audiogon advertiser and supporting dealer. He has the Nottingham and VPI tables, and is a nice guy who will help you out.
