What does that mean? Are you saying the frequency response is boosted at the lower end or the high end has been suppressed? Is not the measured response flat?The balance is more bass-heavy than in previous generations too, and some might want to dial a little of that out from time to time,
This shouldn´t sound any different than X6500H, maybe something have changed in the listening room or it was setup different way. PSU, DAC everything is same as in old model. What Hifi has claimed differences with lower Denon models too, but there haven´t been any changes in the components just few new features. Don´t take these reviews too seriously, they are written to sell these machines.So, this is not really a serious review but just what the person who reviewed it "feels" then?
