Manley Steelhead V1 vs. V2?

Is the line input the only difference between the two versions of Steelhead?
I have version 2. The line input and the power supply having the blue LED vs red are the only changes I have noticed. The tube compliment is the same, and the newer V2 is remote controlled. Other than that they are the same sonically
Thanks for your help.
V1 also has DIN input for the second MC.
