I have a UD7 and it has done the job so far. I would get the UD9 if I could see tangible benefits. The box advertises 24 Phase unlocked power but my UD7 is supposed to have 24 Phase power (version 1.0). There seems to be a version 2 UD7 but with 16 phase power. Is this latest 24 and 16 Phase power outputs something to have or am I just as well keeping my version 1.0 UD7? Is the new Phase designs that good?

I'm sure it's a valid question, simply because of the high price of the UD9.
