Am I too big of a jerk,even for audiogon?

I value the OP because he starts interesting threads, and unlike some he can answer what others might perceive as a Dumb Question with succinct and non judgmental answers.
  It seems as though he might be having a crisis of confidence.  His subsequent posts In this thread quote only his detractors, not people who are supportive.  On lively threads if you stick your neck out there will be some return fire.  The OP seems bothered that there are times when he gets sparked up in a discussion that he makes some posts that he subsequently, upon reflection, wishes he hadn’t.
At least he recognizes this, and I remember several times when he later takes something back, and that’s cool.  The worst thing imo is when people refuse to admit error and double down on their original mistake.

People need to get a life, work, volunteer, do something !!
Read enough to establish the futility of this post.

I seriously doubt the OP enjoys music, unless he considers the sound of his voice as such. Perhaps he needs to be locked in an elevator alone listening to Lou Reed’s Metal Machine music for eternity. 

Mho....
I suspect everyone that haunts this space enjoys music to whatever degree that consists of.  For some, just the 'event' of it, and the ability to do so in their own fashion and means.
Others may relish what I consider the 'esoteric'; the 'hunt' to be able to grasp the discrete nuance of their equipment to recreate a performance to the nth degree....
If being able to hear the 1st violinist breathe as well as play with 'brio', well....great.
Do so...let us know. *S*
Most of us fall somewhere in the Great Middle of the Audiophile Bell Curve. ;)

Wishing eternity on anyone is cruel enough, needlebrush.
As for L. Reed....the OP might like that.  Did you ask?
Hell, no.

The only way we as humans will experience eternity is through death.
That...happens eventually, anyway.
You get to 'go there' too.
Watch for what you wish on others... just saying....

Erik, in my experience you are nothing like a jerk.  Your posts are reasonable and helpful.  I look forward to reading what you have say.
