Bobs SKY 30 (SUT)

Just purchased and installed Bob's step up transformer (SKY 30) for my Koetsu Vermillion playing on a VMI Prime Signature into a McIntosh MA-7900. What an incredible difference in sound stage. This has got to be the best improvement to my system in a long time.  Anyone have experience with Bob's products ?
Yes I recently added a SKY 10 to my system (Conrad Johnson TEA2MAX, ET5, ART and Ortofon Per Windfeld) and could not agree more with you.
