Theta Compli vs Wadia

I am thinking of upgrading from my current Lexicon front end to either Theta or Wadia (used), and would be grateful to hear from anyone who can comment on the how Theta's Compli compares with Wadia transports/CD players.

I currently run:
Lexicon RT-10 multiformat player
Lexicon MC-8 preamp/processor
Theta Dreadnaught II 5x220W
Focal JM Labs Alto (fr), Micro (rear) & Centre Utopia Be
REL Stentor 2 sub
Synergistic Research cables

I hope to upgrade to a better DAC, like the Theta Pro Generation VIII.

I know that the Wadia CDs/transports cost more than the multi-format Compli, but used prices are not that different.
How does the redbook performance of the Compli as a transport compare with the Wadia models?
On SACD, how does the Compli compare with the Wadia 581?

Any comments or advice would be gratefully received.

Many thanks,
