ARC Ref 6 VS. Vac Renaissance MK V

I’ll probably be borrowing a VAC Master from my dealer soon, to compare to my Ref 6. But I saw a photo of the inside and it looked a lot like the Ren V circuit, with the main difference being PSU (much in favor of the Master). The Ren V SE might be an interesting option, since based on the SE vs. non SE on the Renaissance phono stage it raises the parts quality a lot (I think even better than Master in some cases) and makes it sound more neutral and detailed.

Take the one you like the looks of best.

I wonder how the signature mk2 non SE compares to ARC 6 and Renissance mk5.
