No, I think you are misunderstanding me. The comment before yours was basically saying that any time you read universally positive reviews, it's not a true indicator that the device has become widespread yet. The "commercial campaign" is to bring in positive reviews, and that sort of extends to early adopters (with any product) because they are excited to own the thing.
You said "don't hold your breath" for negative reviews. I wasn't sure if you meant that the Femto is so good that nobody will ever dislike it, or if you were being sarcastic and saying that the "initial hype" will never run out because not enough people will ever own it.
Once enough people own it, and the magazines/webzines have moved on, only then will you get true unbiased feedback. That's just the way it works. I don't believe a single headphone (for example) exists that doesn't have at least a few detractors. That includes the best and most expensive headphones ever made - Sony R10, Stax SR007 and 009, LCD-3, HE6, HD800, HE90, Edition 10, etc etc. Most of those are well liked but you can always find someone who disagrees, and all of them have appeared on the "for sale" section for one reason or another.
Anyway, I'm still curious how the Femto sounds. It looks great. Too bad I'll probably never get a chance to hear it.
