I think about this often. Having moved from what once was predominantly AM radio to FM, transistor radios with a mono earbud, 78 rpm records still around, 45's on a mono record player and then somewhat rather suddenly graduating to CD's and all the worst of the audible noise just. . . . gone.
As a DIY'r, my next logical step should be surround sound. More reason to build on to my system. But I stop at 2 channel and instead, focus on other small 2 channel, near field novelties. I have access to multichannel. That's what most of my friends have. Still it's always great to get back home to my own style of listening.
