To the OP,
Some good, and funny, responses, as usual.
Both are great.
To the lfd added posters, you could compare how the music is presented between the lfd and cs600 or vsi60....the sweet lil leben300, while musically great, can't compare power wise to the others, and IMHO is not a good match with c7's, unless you listen at very low volume. Very low.
Good luck!
