The thread has somehow gone on to whether redbook will sound great with or without a particular type of DAC chip used.
Heck, the OP did not even touch on the DAC chip.Redbook still sounds fabulous. Period.
Whatever it is that makes redbook sound fabulous is not the issue here. So, the OP is using an Aurender and he is enjoying his redbook but no, this guy has to come along to say, hey, you should not be enjoying redbook so much because your Aurender is a delta-sigma. WT.....?
