Sound and tests are important, sure, of course. However to me there is a ton more to it than just sound. I want to compare the sound, as good as I can within reason, but I do believe it can be taken way too far. When it gets to the point that we are worried more about that extremely slight, and I mean extremely slight performance differences (I don't say better because to who's ears is it better); but when we worry so much about the ever so slight differences we forget about what is the most important two things. The music and the enjoyment.
We do this to enjoy music. So sound is important but also is the look, the feel, the warm and fuzzy feeling that a piece of gear may give me. If it is the compact industrial look and feel of Benchmark, or the flashiness that some do (
Devialet, Burmester, etc. 
), or the preferring a particular designer such as Nelson Pass in Pass or First Watt; maybe you like the tradition, the history, look and feel of McIntosh. What is most important is what makes you happy.
I have gotten rid of some gear not because the sound was not good, but instead because I just never got a good feeling (i.e. PS Audio). It is all part of the over all enjoyment, the sound, look, controls, the feeling the gear gives you; all is important. This is why blind comparisons are not very important to me. The more I get back into this hobby the more that these two things are increasingly proving to be the most important thing to me.
