Theta vs Ayre

I am putting the finishing touches on a HT system (separate from my two channel) and I am seeking advice from anyone who has compared the Theta David II vs the Ayre D-1.

Associated equipment:

Theta Cassablance II with Xtreme Dacs
Theta Dreadnaught
Runco 1101 CRT
Runco 4404 processor
Martin Logan ReQuests, Scripts, Theatre

Many thanks in advance for your advice.
