Ok...
I don't think @amirm still has to establish his credibility anymore.
Sorry if I misunderstood you, but: Are you suggesting that he has to measure ten ranfom units of the same product to assure this one performs well or bad? Because that won't happen unless some (you?) have enough money to buy these units from different retailers around the world and, then send these to Amir...
Please understand this; as is the case with the Global Audio Press, same goes to all the Audio Forums etc; credibility has to be earned every day over and over again.
What I am saying here is that when a manufacturer is in direct contact with Amir, that is one possible place to compromise the credibility. Therefore to avoid this dilemma, all the equipment should come from a consumer who has bought the item.
Anyway whatever he decides to do is drawing the lines and creating a policy which eventually either supports the credibility or not.
