Forgive me for revisiting a subject which has probably been covered, ad nauseum, before here but has anyone here ever heard any difference between CD quality audio and so called "hi-res"? I have compared them and concluded that either there is no difference or that the recording quality eclipses (by far) any difference which might be attributed to the bit/sample rate. The reason I bring this up is that there is some buzz online about music streaming services (Hulu ,Amazon, etc) offering "premium audio" music (at a price) in "audio quality higher than CD". I think this is bullsh!t. Pure and simple. But I would welcome any other opinions here.
