Does other Audiogon members' opinion carry any weight for you ?

Yes, generally...

I tend to discount posts by some that show little or no empathy for others. 

Posting for me is largely about helping others. That requires empathy.  How can anyone advise others on what may be best for them without empathy?   

Just because something works for me does not mean it will work for anyone else and vice versa. 

I believe it’s important to understand that and provide feedback to others that considers their unique scenario and preferences, which may or may not resemble mine. 

Each case is different.  There is no single solution that is best for all. 

People that lack empathy have difficulty understanding that reality.  Rather they expect that what works for themselves works for all. 

It’s the source of a lot of conflict in the world.   Good sound may be a relatively trivial topic in the grand scale of things, but the same rules apply.

I am empathetic with everyone naturally, at least i try, i try to stay positive and nice but i like to discuss even uncomfortable truth sometimes, i admit this point,  in my own passionate way (as acoustics basics being the root of our hobby not purchasing upgrades) once this is said,

 i think as  Nassim Nicholas  Taleb, that :

«if you want to be at once rational and ethical, you must have the courage to accept that being nice to an ass...e is equivalent to being an ass...e to someone nice»

I think Taleb is right but we must begin by being nice ourselves to everybody, if not it will be impossible to distinguish between nice people and  not so nice one.

mapman said it well in one sentence :

There is no single solution that is best for all. 

This is true.None of us had the same goal, budget, gear, room, and wife...

But for example , acoustics science is the basis of audio, not the inevitable upgrades race and  it is not a debatable question...

Then i cannot go back on this point just to be nice...

 Once this is said i value the opinions of everyone here even if i disagree or even if will not take it in account for purchasing or to fine tune my system/room, i value others opinion as  different valuable human expressions which add something unique to aspects of society and humanity...

There are a number of posters who know what they are talking about and whose opinions I value.
On the other hand there is one in particular who makes lengthy posts which are full of rubbish, off track and who has no understanding of what a PM is. And there are some who would be better off on ASR.

There is dude, laoman,  also who send mail of insults and harassed me  in private mail...

He just wrote an hypocrital post above without the courage to name me...

If we analyse my post text information content with many referential articles versus the idiot sending insulting email in my private box the matter will be settled easily...

 Sorry but i defend myself  when someone attack  with falsities and even with just  insinuation ...

By the way i learned a lot when i discussed rationally with some ASR member here...But laoman is unable to learn from someone with whom he disagree it seems...

 I welcome everyone ... Amir included ... If they dont imitate laoman with harassment and no arguments save insults...
