I am very grateful to have made the jump to streaming/file playback. I likely never would have discovered on disc the fantastic - and I do mean fantastic - music I now enjoy if I had stayed with the silver discs. I can still play them, but the enjoy�men of so much more music is very worth the effort to get going with streaming.
With the advancement of the streaming setup, there is not much gap at all in performance between CD and streaming. I still have a transport ready if the music service or Net goes down temporarily, but I do all reviewing with streaming and file playback. At one time, when I used a Mac Mini and upconversion software the quality was not ready, but now, it's all plenty good.
Jim, if you heard the benefit of doubling speaker cables, that's nothing compared to Schroeder Method on ICs.
