DaltonLanny, this almost looks like one of your old threads from a few months ago. Hey, are you running reruns? :)
I've owned both the X-1 and X 2.5 and I would suggest that the X2.5 is about 98% the performance of the X-1. This is by no means meant to slam the X-1, but is more an accolade toward the X2.5. In all, I believe both Pass Labs units are excellent products sonically.
One note is that I always used my highly-rated Foundation Research passive and dedicated in-line power conditioner with both units. Therefore, it is entirely possible that any improvements with such line conditioning the separate power supply with the X-1 may be negligible at best.
-IMO
