It was closed because Amir prefers his site to be about audio gear discussions rather than skirmishes over different web sites. He’d prefer that the emphasis NOT be on attacking other web sites, including audiogon. Funny you are trying to spin that as close minded or dogmatic, while people here continue to attack ASR.
I hope you don’t take offence, but I’m a bit less sanguine about that. ASR’s founder closed their corresponding thread a short time after my last reply to him, and more specifically after @laoman posted Darko’s letters page including his exchange with Amir. My experience is that he often closes threads when he realises his views won’t be the primary focus or won’t prevail.
In the thread on that exchange at ASR, I suggested to Amir that going for the jugular against Darko’s previous guest (Cameron aka GoldenSound, with whom Amir has previously engaged, demonised and banned on ASR) was tactless and made him look like a bit of a nutter (I think Darko likely concluded that an hour or so conversing with Amir would be less than edifying and demurred). Amir said he considered a more tactful offer too much of a compromise. Darko asked if being right was really worth the aggro. And so on. I doubt Amir wanted to re-visit that episode here.
He’s not shutting down discussions between "subjectivists" and "objectivists" on ASR: there are tons of threads on the subject, even stickied threads that are endless debates.
The sticky thread on measurements at ASR (for example) is a declared catch-all/resting place for posts (moved by moderators) that originally appear in reviews and an attempt to contain criticism/discussion of ASR methodology. Sensible to do that I think, but I wouldn’t interpret it as encouraging said discussion. It’s more the case that objectivist vs subjectivist debate would take constant vigilance to suppress, and that thread is an easier option.
But keep these comments in context, there's a fair bit of good info and discussion at ASR. It's a rough with the smooth thing for me.
