I once asked 6 guys who were working in CD shops which locate in Chicago, New York, Baltimore, Boston, Los Aangeles, one of them is supervisor, did they have SACD, nobody understood what I was talking about.
A lady once asked me:"James, do you think is there any difference between a US$500 system and a US$5000 system?" I could say nothing, as I knew any explanation to her is just a waste of time.
Last week, when I talked to Dave, a typical Aamerican, about my new gear ( a pair of JBL4622 for my home theatre), Dave said:"You are crazy", that's all.
