Have you got a good FM roof aerial installed yet? If not, that will be a much bigger improvement than swapping one Denon tuner for it's MkII version.
Assuming you already have a mast for your DTV aerial then it won't cost much for a trained fitter to pop a vertically aligned half-wave dipole up there. (It will do a decent job with DAB too if FM gets cut off at the knees anytime soon.)
