Amp Basics: Tube Preamp w/Solid State Power Amp.

Hi, need some basic information. How does one ensure a proper matching of a solid state power amp w/a tube preamp? The tube preamp I am considering has "low" 12db gain (PrimaLuna Prologue 3).

Does one have to be concerned with the wattage of the power amp (being too much)?

As well, what is a "class A" power amp?

Any good suggestions on a SS Power amp in the $1000-2000 price range.

Thanks, any help would be appreciated.
