Well gentlemen, thank you for all the good advice but my intent was not to raise the ire of one against the other. There is certainly enough of that going on in the world at the moment. I respect strong opinion but also hope we can agree to disagree - all ears are not the same. I appreciate all of the input from everyone and certainly we all enjoy what we enjoy.
Unfortunately, as much as I would LOVE a side-by-side comparison, it isn't likely to happen. I have bid (and lost) on several options suggested. I will install a new Shure VX15mxR as my base level and go from here. I hope to someday win a Shelter for a reasonable price as well as a ZYX. I haven't tried for a Denon yet but I think I will. Unfortunately I'm not a Denon fan on the electronics end as I find their equipment shrill and digital - if that makes sense. I think I have a system that can distinguish the differences in cartidges. I have my GyroDec finally set up well, although I am awaiting my digital scale for the final setting. My Scout is also ready to go - it's my system that isn't quite there pending finishing a renovation of a family/home theatre room.
Anyway, enjoy everyong and my thanks for your input. If anyone knows where to find the needed cartridges for bargain prices, let me know. I intend to buy some and sell what I don't want to keep.
