If that has been the case, no doubt you got replies because I have seen it from time to time. Seems to me that was exactly the thing that prompted @amirm to post this thread in the first place.s. It only makes it tougher, and even worse, makes the hobby far less attractive than when I first started. I don't know how. Fine. Doesn't give you free rein to berate me and tell me I don't know what I'm doing because I'm new.
My two cents, people that post things like “I can’t believe you don’t know that” or something similar probably don’t have a real understanding of what you are asking anyway. Their participation here isn’t to learn, or spread knowledge, it’s to hear themselves talk and/or show everyone smart (they think) they are. There are exceptions of course, but generally I think that’s true.
You would never see an Audio Luminary, Expert, or other person with one of the designations respond that way in here. Sorry you have had to deal with that.
Even more sorry if we are moving away from the spirit in which the original post of this thread was intended. My impression was we had turned a corner, for the better, when this thread was started.
