help me decide: VTL 7.5 or ARC Ref 3

Hi, I am currently contemplating these two preamps. My reference is the Einstein The Tube preamp. Both of these sound pretty close to the Einstein. I would greatly appreciate feedback from owners of either preamp (past, present, future). Also, which one is more tubey? I have heard the Ref 3 and it sounds great. I have not heard the VTL 7.5 but have heard incredible things about it.

Thanks in advance.
