When you say "newer" you mean the stuff I bought today. I guess the stuff I bought last week is old huh? In audiophiledom you are the lone voice.There are BIG,BIG differences. Low,mid fi,maybe not. Go to a high end store, an ask for a demo.Ask to hear a toslinc between Jadis digital gear pieces. Sorry,I have this mean streak. Like I always say,"If you can't hear the dif. don't buy it"
