At times I must come off as some sort of audio-curmudgeon, such as when I became upset when I noted some audiophiles calling a component a preamplifier rather than a line stage. There have been other times, too, that I've gotten upset over someone using what I consider the incorrect nomenclature for an audio component or part. Thankfully, I've gotten over that preamplifier versus line stage episode. But I'm still working on the fact that some sell speakers that they call "subwoofers" yet don't go below 20 Hz. "Sub" what?
