Okay, I guess the issue is "satisfactorily".
Yes, I have found that the Timefactor indeed functions with the voodoo lab ISO-5. The problem is one of a reduction in performance of the Timefactor that is evident with my high quality equipment.
I didn't realize that changing power supplies could affect the sound like it has. For me the Timefactor is unusable with the ISO-5 and as such I guess I wish I hadn't spent the money for it.
The Eventide transformer is large, however for me it is worth every cubic inch of its size for the great sound that it allows the Timefactor to produce.
