My ears of tin are over 50

Agree with Musicnoise. And let's not forget that sound differences are still apparent to anyone short of the totally deaf; thus even my 65-year-old ears, even with a hearing dip at 3k, can still discriminate and be pleased by some sounds more than others. Just like you kids!

Who is Jim Smith,and should we care what he says?

Is that Dr. Jim Smith?

His website is www.getbettersound.com

There is some good info on that site.

At 80+, my ears are far from perfect but I'm still buying hardware and software regularly and enjoying the hell out of what I CAN still hear. 50-year-olds are babies! Dave
