jkphoto is right--there are many ways to get not just sound, but music. in terms of "entry level" tube amps--none are more musical than cj's mv55. it was my first tube amp and i listened to quite a few before i bought. i recently left it (after nearly 3 years) in favor of a more powerful cj tube offering. check the reviews at audioreview.com--this amp (stereophile class b) is nearly universally loved as a cost effective, reiable and very musical intro to tube amps. as always, testimonials and stereophile class designations are helpful, but you and your ears should make the final call. good luck.
