Transport to replace Arcam FMJ-23T

I am presently using an Arcam FMJ-23T as a transport to feed my Dodson DAC-263. What transport in the 1000-2000 range would be an upgrade from the Arcam?
Theta Data Basic II is one of the best transports ever. You can find it for about $600-700 used.
I'm thinking that your arcam uses a very highly rated sony drive. It might be hard to hear an improvement with any replacement (beware, this is a biased opinion as I'm of the bits-iz-bits persuasion).
Proceed CDD ,available for very little used and the MLevinson 37.
I currently use the 37.
