Solid State Monoblocks-Tube Preamp or Solid State?

Assume you are starting to build your system with solid state Class D monoblocks.

You are now looking for the best match as your preamp. Which type will you search out? Solid State or Tube?

What factors do you put at the top of your decision making process?

Would Classical Music lovers prefer a tube preamp in order to bring some warmth and softness to the solid state amplifier components? On the flip side, if Rock and Roll is what drives you. Would you be looking for a solid state amplifier because it benefits from faster switching than tubes can provide?

Or, does your musical selection not enter the discussion. Could it strictly be an equipment compatibility issue? Any worries regarding tube failure in the preamp causing damage to the solid state amplifiers.

My monoblocks are Spectron Musician Mk iii's. I am leaning towards the Joule Electra LA-150 or LA-300, but still have some concerns. Any other preamps, solid state or tube? BTW, speakers to be used will be the Gallo Ref 3.5's
