Prcinka referred to phase reversal in the first response to this thread; but it was never followed up. With use of an absolute phase switch I have found DG records to be generally very good, certainly above average. Being able to listen to a record (or CD/DVD) in normal and reverse phase allows one to select which setting provides more clarity,nuance,dynamics and a deeper view into the soundstage. I think many of the negative comments would disappear if the listeners had the chance to choose the setting they prefer.
