hello P
just an update:
having a day off today and now Iīm listening to live at blues alley with eva cassidy and have tried back and forth with or w/o upsampling and in my system itīs no doubt: quad and AP gives the reproduction more detailed ambience and realistic sense of space
the voice and the applause is also presented more free standing from the acoustic venue
nobodyīs frying bacon here

the applause have substance and body
bass is also more nuanced and easier to follow
and then I donīt really give a rats ass what works better in other systems;
like the true ego I am;i only care about myself and my system
well done
best
Leif
