i auditioned the r7 metas with a hegel 390 and my impressions were similar to @photon4--very wide sweet spot and big soundstage, good overall clarity and very sensitive to cabling and pairing. esp. to my ears they were a bit polite (comparable audio physics and proac had a little more oomph), and given their sorta plain appearance, i thought they were a tad overpriced for what they are--they didn't overawe me, but certainly a quality product.
