I have a V1 EP600, and had to get a new amp as well, i now have the new version of the amp in my 600... The biggest difference between my old amp and the new one is the math that they used for the gain adjust.. in the old amp they used a cube root function, in the new amp they are using a logarithmic function.
The audio terms are front end loaded (most of the increase is at the beginning of the scale) or back end loaded (more increase at the end of the scale)...
One other thing of note, i think the transformer on the V1 amp was considerably larger than the transformer on the new amp ( i could be wrong though)...
At the end of the day... I "think" i like the old amp more than the new amp, but i am not sure.....
