It’s a curse having an electrical engineering background. It holds you back from getting a great sounding system. You think too much about things, using that hard-learned logic to persuade yourself that things can’t possibly work. I was similarly afflicted, but have now learned to listen first, then having decided if the difference is there, and is tangible and worthwhile, then use that engineering background to work out what’s going on - how can that work? You have to think outside the box too.
I have a much better sounding system now, and better understanding of what matters.
the awkward middle ground, the 'never-ever land', related to this discussion is the (fair and scientifically well established) argument that when our minds are very strong, and can affect our senses and our perceptions, so sometimes if we are not careful we hear what we want to hear
so if we are not rigorous and careful in how we evaluate a system change, we can and will fall into this trap of sorts -- i think this is an important factor that many in the industry take advantage of, when it comes to selling 'improvements'
