I would not call the SA6s a FOTM. The vast majority of owners find them to be the real deal, so that comment is over the top. Do you consider the Atrios a FOTM? Doubtful. Yet, they are generating nowhere near the interest they did a year ago? I know I don't believe they are a FOTM phone, even though I sold them. In most cases, general interest wanes over time, and that's all this is. I don't sense any stampede to dump SA6s by owners/supporters (a la V-Moda Vibes).
As for the RE1 being in the same category, they are barely out of the gate, so they don't qualify, not even close. And as you've seen so far, the RE1s pretty much require an amp to shine, while the SA6s don't. So they aren't really in competition based on usage style. Plus, at least right now, there is a $100 price difference. The comparisons are just made by one poster, who likes them both.
Anyway, FOTM is a somewhat negative term, for gear that goes from great to bad, in my view. No reason to label either of these phones as such, since they are both quality pieces of equipment based on user feedback.
I am not being oversensitive here, just think flip comments don't really add much.
