If I had a choice
I'd be listening to the original CDs & LPs, but I spend my days driving around South Carolina and do most of my listening in the van, so I need something a little less bulky. I'd rather use a less lossy format than mp3 (with better compression), but the player I have only recognizes mp3 and wav formats.
I sample at the high rates because the dynamic range suffers at the lower rates, and I like hearing the louds & softs.
