CAT SL-1 questions

I've been researching these pres and I have three basic questions-
1. Whats the diff between SL1 Mk1, 2, 3 and SL-1 Signature.
I know that the SL1 Mk1 had a rep for eating tubes, which suppossedly was tamed in the MK2 and 3. Is a SL1 MK2 more desirable than a Signature MK1?, etc.
2. Does the phono stage of an SL1 or an SL1 Sig have enough gain for a Benz Glider low output (0.3 mv)?
3. Anyone ever use them with McCormack DNA 0.5 Rev B or Rev A?

Thanks for your help.

I'll try to answer some of the questions: The Signature has even less noise than the previous models. The Ultimate has a better sounding phono than the Signature. The line from the 3 onwards is very good IMO, with dynamics and musicality winning over analysis.
Some of the changes are due to using different tube biasing and manufacturer of tubes...
The phono is quite flexible with loading and should drive your Benz. I used the Ultimate phono on a Clearaudio Accurate w/out difficulty.
