The big Tannoys are lovely! As per amplification and given the plethora of choices out there, I would recommend any class A topology that suits your sonic tastes -- simply because that topology requires high VA power supply reserves. These are useful in taming the "thickness" chang refers to above.
You will also use twisted single-core copper wire (16 or 18gauge) for spkr cabling, of course, as a reference.
BTW, S23chang WHICH Jensens are you using on the GRF?
I'm not sure about the need for a preamp unless you use a TT.
