Would like your tube amp recommendation

I've got Magnepan 20.1s, PrimaLuna Dialogue Premium preamp, Accuphase P1000 SS amplifier, with digital source (Byrston BDP1/BDA1).  It's a pretty sweet sound, but looking for something a little more musical with a larger sound stage.

I like the PrimaLuna preamp, and was wondering what to expect if I replace the Accuphase with PrimaLuna Prologue or Dialogue monoblocks.  Would they drive the Maggies?

Thanks,
Richard
