The overwhelming majority who have posted on this thread who actually own the K812 have posted very positive feedback. Many who were at first concerned about the treble issue have posted that given burn in time, it's hardly an issue at all for them. The most negative posts have come from people who don't own the K812, and should be taken with a huge grain of salt. I would give much more weight on the comments and real life impressions of those who live with the K812 everyday over some who are little more than negative naysayers who can only find fault with a headphone based on one review. There are a number of pro reviews on the 812 out there now, and they have all been positive.
Is the 812 perfect, of course not, nor is any other headphone on the market. But these sound damn good and deserve to be heard before judged.
Having followed the thread from the beginning, positive impressions outnumber negative ones but not to the degree that you represent; and it's inaccurate to charge the negative impressions with inexperience and bad faith.
Very positive impressions, such as yours, outnumber very negative impressions, but that is to be expected in an appreciation thread (except for a few trolls). Bear in mind also that most of those who posted negative impressions or mixed reviews have unsubscribed already, which makes the balance seem more positive than actual public opinion.
The obvious fact is that very few here, having heard it, have decided to buy; and most who haven't tried it, have lost interest in favor of the new planars, which is a pity.
