Blind Listening Evaluation

I wonder if "identical" units sound the same considering the variables involved with parts (quality and calibration) as well as workmanship.

Dekay: Fair question; no two units ever measure identically, for example. But barring construction flaws, units tend to measure within very tight tolerances. (Speakers can be an exception, but nobody ABX's speakers.) If so, and if they cannot be distinguished in an objective (e.g., ABX) test, they would qualify as "identical" in my book. And if a company were putting out a product that sounded different from unit to unit, why on earth would you buy it?

Jostler, although we often agree to disagree, both posts show your usual excellent reasoning: Short and to the point Kudos to you.
