Thanks for taking the time to explain it without asking me stupid questions like
"Why would I need one? Original dynamics of a good recording not enough?" followed upwith an intelligent "exactly"
I admit I was only 18 or 19 years old back in the early 80s when I heard my friends setup who ran his stuff thru a dbx. I didn't have time back then to a real sit down comparison of having a compander in and out of the system.
I did look at the dbx website and its all pro-audio stuff now. It would appear that the compander idea for home audio died when the format changed to CD.
