Is positive reinforcement why things are sounding better?

I would say that if you are hearing things that you were not hearing before, or even hearing things in a different way, it may not be confirmation bias.

Just curious if positive reinforcement experiences have occurred for others, and how can you really tell?

Well, just thae fact that you are questioning it makes me think that it is probably not confirmation bias. 

I have a hold of a few preferences, but one of my experiences with hearing new systems is getting a new idea of how something can hang together beautifully

+1.

i post this for the benefit of all. I dont hope the harassing idiot

who trail me in all threads  is in a state making him able to any understanding ..

Actually, @mahgister  , I do not "trail you in all threads."  I try to avoid you.  It just so happens that I commented in this thread prior to your rambling diatribes, so maybe you are trailing me?

you came uninvited for example in the thread "the mystery of sound is mysticism " where you never posted any positive contribution expressely to derail the thread with sarcasms

@mahgister , alluding to that particular thread: Audiogon Management sent me my invitation via certified mail; they did not provide a list of everyone else who they invited, so if the invitation you received was in the same format as mine was, you would not have known that I was also on the list. And you are mistaken; the only two (quite short) posts that I made as I was following that debacle were not intended to be the least bit sarcastic--I was serious.

To the topic of this thread: confirmation bias, as it relates to audio, involves telling one’s self that one is hearing something that one is not actually hearing. Basically lying to one’s self.

I will not even answer.

That would be best, since you would be unable to refute it.

Anybody can verify what i said about your behaviour consulting the thread last 2 pages "the mystery of sound is mysticism".

As I typed previously:  there was no sarcasm intended--I was serious. 

Would it not be illogical to buy a speaker that I did not like to hear?

It would not be logical to buy a speaker that you did not like the sound of, unless for whatever reason you were able to convince yourself that you did like the way it sounded.

@tonywinga  , I don't think anyone is trying to say that all percieved sonic improvements are a result of confirmation bias.

I just ignore those (bots?) who make random, semi-literate grunts. Saves my time.

Good plan.
