I concur that measuring is not always best. For instance, my abdomen. Measuring it, strangely, induces an anxiety which causes me to whimper, moan and seek the comfort which can only be found at the bottom of every Ben & Jerry's pint. In converse, when I remain oblivious to the exact metrics, my mood remains elevated.
We should shut this whole forum down, start wearing berets, and get a group subscription to Audiophile magazine.
