Mcintosh C-2200 phono stage

Any body been sucessful tube rolling the phono stage of a C-2200 Mac? The phono stage seems very rolled off at the frequency extensions with the stock tubes and was wondering if anybody was able to wake this thing up with tube rolling?

I woke mine up with a solid state phono preamp.
are you using an mm or mcho on your table?...i only ask, because my c22 reacts differently to each in the treble regions, while my revox ss doesn't.
