I too rely heavily on both instrumentation as well as my ears. Note that there is much work yet to be done in the area of psychoacoustics, and that there are still things we can hear, but can’t yet measure. In addition, we have a hard time correlating what we measure with what we hear, and an even harder time communicating it. Just think of how poor our current audio perception language is. In my opinion, audio perception terms are in desperate need of standardizing. When we talk the same language, we can expect better understanding and quicker advancements.
