Best all around speakers

Just curious what people think around here for best all around speakers for wide variety of musical genres and amplifications needs (tubes and solid state). Not everybody listen exclusively to Diana Krall and Norah Jones and/or acoustical jazz or classical music. Some of us like to listen to a wide variety of music (from rock and roll to bluegrass to blues to you name it) and don't feel the need or want to have a differet speaker for each genre of music. Seems to me many speaker designers have a very narrow taste in music, which unfortunately doesn't reflect what most people listen to, which I think is one of the reasons why many speakers end up disappointing quite a number of listeners.
