Upgrading my system? Levinson to. . . . ?

I'm considering the following changes to my system. I'd sure like some feedback/comments. I have three options in mind.
1. Keep the system as is. I love the sound as is, but think I would benefit from some better amplification.

2. Upgrade my system by swapping a pair of Levinson #33 amps for my two pair of Levinson 436. This is the one I'm favoring. The 33s would be older but I have a chance to own one of the best amps in the world to drive my Salons with.

3. Selling my DAC, Transport, and Preamp and upgrading to a Theta Gen VIII and Compli and maybe even switching to the Theta amps. I'm really interested in the Gen VIII and Compli so I could upgrade my digital, and use the Gen VIII as both DAC and Preamp thus making my system newer and simpler by not having a preamp.

4. Of course if there are other ideas I'd be glad to hear them.
