We have the same expression. Read my review then read Rob Watt's reaction to it. Tell me who is using vinegar then. I praised the good that the product presents. He returned no such favor.
Look, you can't go to every audio show, give a 1 hour presentation based on objective metrics of filtering and then fantastical claims of -300 dB and then expect folks to invite you for dinner when facts don't back those up. Add the thousands of dollars that this product costs and reaction is all but certain. Nothing here is about Rob, what home he lives in, what he does on the side, etc. It is all about criticism of his work and claims about audio.
Personally I think he has done a lot of damage to understanding of audio with those talks and posts on head-fi. In that regard, he should get strong push back when reviews like mine pull back the curtain. This is doubly so when he said about my previous reviews that he had not even read them, and now ridicule my measurements and work. You can't set yourself up for harsher criticism than he has. This is a pattern we saw from Schiit founders before they retooled. And likes of Danny from GR Research. Talk big and not speak the truth and folks will react strongly.
As I have said and repeat again, members of industry need to act professionally. Nothing good ever comes out of being flippant and rude toward the reviewers. When I was in product development, there was a reviewer who wrote for PC Magazine that was completely in the pocket of our competitor and hated us with passion. Yet, I stayed polite and eventually got him to write that our product was good as well. If I had acted like these people do, that would have never happened. That British "stiff upper lip" does have merit at times and this is one of them.
Mind you, just like Schiit, if he produces truly competitive products, I will praise it regardless of history. He should act the same way.
