No....not in my case as I   got someone else to do a disc for me. This was sufficient to convince me.

I have not the foggiest as to why the same machines appear to be giving different results...though its not unknown to hear the same player in different system do different things.

Its interesting to note that bottleneck found no difference ...did  you find the same with some of your other comparisons recently ?

Which may suggest other factors are involved ...of which I can't shed any light on. 

Its like a lot of things neither is wrong ....but I prefer lathed discs to unlathed ones...to the point where they are sounding lifeless  actually souless may be a better term ?
