A good bass sound is appreciated by classical fans as well. I have quite a few CDs of organ music (organ pieces or choral pieces with organ accompaniment). If you have a big piece like Liszt's Fantasie and Fugue on B-A-C-H or a good English organist accompanying a cathedral choir singing a psalm to an Anglican chant, when things get really warmed up and the 32-foot stops go on, the floor in my living room vibrates up and down, flowers sway in the vases, and the pictures rattle against the walls (and the music isn't terrifically loud).
