A few thoughts from a random nobody (me):
Amir allows and encourages active discussion of all products as part of the thread where each of his reviews actually appears. He himself participates in the ensuing discussions, and often does followup tests or seeks input from the manufacturer where possible or where the product's manufacturer has a representative among the membership here.
Anyone who plans to purchase a product based on Amir's review on this site has easy and convenient access to any discussions of known or potential issues in the very thread that is supposedly influencing all these buyers to their peril. How can creating additional threads with increasingly hysterical/hyperbolic demands do anything useful? If someone is apt to be persuaded by a review to buy a product, the best place to warn anyone of a negative experience is within the thread that began with the actual review in question. The person who reads the review and wishes to buy the product may not ever see the additional threads, so the usefulness of warning others is questionable in my view. It starts to look more like someone trolling Amir or trying to embarrass him on his own site for recommending a product that others (we do not know what percentage of owners) have had a bad experience with.
If someone purchases the product on Massdrop, that person is free to warn others of a bad experience in the discussion section there, or even better, by posting a review there. Looking at this Topping product on Massdrop, I see that there are 10 reviews from verified purchasers, with 2 of those saying their unit died, one within 3 hour and one within 3 weeks, who said he returned it. In the discussion section there, several others have made comments about issues and at least one linked to the discussions here on ASR. Massdrop shows 239 units sold, 307 discussions, and 10 reviews, by the way.
So how do additional threads on this site serve a useful purpose, when Amir has not restricted any discussion, and his own original review thread amply covers his own experience with his unit, and the experiences of members?
