delta 66 vs. motu 828 or digi 001?

[le french cowboy]

Is there a big difference about the sound quality of these 3 sounds cards? I have a delta 66 and was looking to upgrage with one of these two or a card in the price range of 1000$-1500$.

Thank you

I'm also interested in the Digi001. I've been unable to find any in-depth reviews. I'm curious about the quality of the mic pre's as I've read the M-box pre's are pretty lack-luster.

I'm running a Delta 66, and have been pretty happy with it's sound quality, not that there isn't room for improvement. I'm thinking of upgrading too, and from what I can gather, the Lynx cards seem to hold the best promise that I'm gonna clearly hear what my upgrade money went for.
