I listen to either all multi-channel music, or 2 channel processed by PLIIx (never use the panorama-type 7-stereo mode, so can't comment on that) . The QS8s do an amazing job reproducing the ambiance extracted by Dolby's technology. But even the more direct mixes of DVD-As and SACDs are still beautifully handled.

Don't worry about the QS8s with music.
