Bachus,

The only option to even attempt replacing all that gear in an all in one solution is the Wersi Sonic. A Verona, Abacus, or Louvre will almost get you there but to run more than 4 VST's at once, you'd have to forego the Wersi VST host which I don't recommend.

I've never thought of upgrading until I saw the specs on the Sonic. That might get me to move up from OAS7. I won't know for sure until I hear and see more of the Sonic. Wersi definitely has the edge when it comes to pushing the limits of today's technology.

The only other keyboard I've considered in the past 5 years is the Fairlight CMI30AX. Unfortunately it's on hold right now with no definite date for delivery to market. The FPGA processor the Fairlight utilizes is unrivaled in both processing power and sheer audio quality. If you've never heard the Fairlight CC1 card in person you can't fathom how great it sounds. Truly the pinnacle of digital audio.
