With my Mac C2500 and MC302, I have a very deep and wide soundstage that goes way beyond the speakers. I am using the stock McIntosh branded tubes (new), with are JJ’s. I tried a quad of matched NOS Gold Lion 12ax7 which were graded as “uncle Kevvys stash” from Upscale Audio. After using them for 4 months, I went back to the stock tubes which to my ears gave me more of what I was looking for.
I chose the Gold Lion because that is what almost everyone in the Mac group on Audio Aficionado loves and recommended. I haven’t tried other brands as I am satisfied and it’s a PITA to remove from rack, disconnect everything and carry to kitchen table to unscrew all the screws.
