I've had a 20X-H for several years and recently replaced it with a very lightly used XX1-H (yes, they made a high output version of this). The XX1 is now updated to the XX2 in the DV line.
Now I know this isn't a MM, but I can say that there is much more resolution and inner detail and just better overall (and still musical) presentation with the XX1, as you would expect when moving up in the line. However I can also say that I seem to have lost some of the dynamic expression that I loved about the 20X. It is a very good cartridge for the price and probably one of the best deals under $1000 these days.
I couldn't go back to a MM after hearing these, and I used to be a Grado guy.
Enjoy,
Bob
