I recall having a similar reaction when switching from VPI to Basis. They are very different sounding tables. Though I wouldn't say my reaction to the Basis bass was horrible, no balls. I do recall thinking to myself "what happened to the bass?" After extended listening, I realized that the bass was still there with the Basis, but it was tighter and better defined. The VPI's bass is full and warm, which some may prefer, but after listening to the Basis it can sound wooly and bloated with certain gear. As with all things in this hobby, it's all about synergy.
However, looking at the rest of your system, you may now be too far in the direction of speed and resolution. Since the Basis is much faster and higher resolution than the VPI table, when mated with ARC electronics and Nordost cables, also both noted for high speed and resolution, perhaps you have now passed the tipping point in system synergy. Fast table + Fast electronics + fast cables = too much speed, not enough musicality. Perhaps in your system, you may be better off with a VPI table.
What cartridge are you using? Perhaps a wood body Benz or a Koetsu would sound better with the Basis, and/or perhaps a Purist Audio phono cable.
Also a good suggestion by Arh to take the table off the Vibraplane.
