@jasonbourne52 - My experience aligns with yours and the box somewhat because I find that differences are very small when switching back and forth. I find the biggest difference when I’ve made a change in my system after listening to it for months. In this scenario, some changes become very obvious to me while others don’t. It’s not possible to use any system other than your own as a point of reference in my opinion when evaluating things like cables.
Example: I struggled to really describe any difference between AQ Sydney RCA and Monoprice XLR in my current setup, but the move to Morrow Audio MA4 was clear and obvious to me.
