Tube amp for a somewhat difficult load

My speakers are Hales Concept Fives rated at 86db/w/m 6 ohm.
I am looking for tube amps that will give me the tube sound, or is this futile for a speaker of this nature and am I just wasting my money? These speakers need a minimum of 100 watts with solid state. My room is 24 X 16, and I listen to mostly classical music.
