I recently purchased an 01V96K mixer, which replaced a MixWizard 16:2. Yamaha reps will tell you the pre's in the 01V don't compete with the DM/M7CL/PMD consoles, although they are actually pretty good. I recently used the console to drop live concert audio into a MOTU Traveler and DP4.6 software, and the audio was stellar--far better than I ever got out of my Wizard using direct outs in the analog world. Sure, it wasn't as good as a DM1K/DM2K, but what the heck. You have to look at the entire system to make judgement calls like that. Can you really tell the difference between the pre's of each mixer through anything less pristine than studio monitors? Probably not.
I honestly miss the EQ of the 'Wizard' for quick "down and dirty" sound checks, even though the digital EQ is much more flexible. Add to that fact that the 'verbs are far better than the Wizard's, and that you get a decent compliment of dynamics processing, built-in output delays, and patching flexibilty ad nauseum, the 01V is honestly the better way to go. If you MUST have better preamps, then just consider adding a card and a couple of MLA8's. Then you'll have 32 channels at your disposal, 16 of which are pre's based on the DM2000!
