Hi George

I'm using an analogue system (see my profile) so the brightish sound of the g68 could be a chracteristic of the DACs. DVD audio, however, is superb so it's difficult to blame it all on the DACs.

When I say bright I include the upper mid which as you say gives increased sibilence on some vocals. Nothing too unpleasant in my case just markedly different from the 500 series I'm use to.
