I agree with the idea that a sense of scale is important, but I’d trade sexy for scale, and you can usually get that from a single speaker shot.
Take a look at the picture I took above for instance. Nothing in the room gives any sense of scale at all except perhaps the power strip to the right of the amp. In this case I don't think we can tell much by seeing it all.
I'd prefer show coverage to be sexy first, and encyclopedic second honestly.
