It can come across as shilling, even if it's intended in good faith, to have it show up over and over and over is an unusual pattern. You go around other threads and there's plenty of cross-talk (forgive the pun) but it's never so directed and continual about one particular alternative like this. Not even the first Sennheiser thread with it going on - it was even more out of place in the original 660S thread since that headphone has for some time now been more of a ~$300 can, half the price of the oh-so-vaunted competitor.
Plenty of good points have been brought up by members here as to why the two headphones HD-6602 and NDH-30 bear comparison and I'm not arguing against that, at least this time there's price parity - but man, it is a heavy layer nonetheless. I know y'all are different folks but the evangelistic pro-Neumann angle is so consistent that it can read at times like it was all written by one person.
It's great that it has made such an impression on owners, but that discussion seems to take up all the air in the room when it comes up, total derail in places. But, it's not my forum, I'm not trying to moderate anybody, just mildly exasperating if that's not the discussion you came to the Sennheiser HD-660S2 thread for.
I dunno, it probably isn't totally fair of me since comparisons to HD-600/650 don't bug me at all, and the Neumann is kind of a Frankenstein's monster of Sennheiser parts from the acclaimed former Sennheiser designer - I get it - maybe one day I'll try it and my third eye will open and I too will be shouting about it from the roofs
