Best tube AM/FM tuner

I am currently using a Yamaha CT610 II tuner and, while I like it for the 20 bux it cost me, I would like something a bit better and possibly a tube unit. I am thinking McIntosh since they hold their value well especially if you acquire one in nice cosmetic condition. Only problem is the only tube McTuner I can think of is the MR65.

I understand from my review of the fmtunerinfo website that Mctuners are pretty good but not "the best" by any stretch. I am willing to have the thing modified/upgraded if that is what it takes. Anybody here with extensive experience with tubed McTuner units pref the MR65??

Thanks,
Carl
