The thing is that agreement can happen simply by bandwagon effects, but that is another thing that if brought up would get you outcast. As far as the flame-war element brought up previously, my feeling is that 1000+ page threads can deal with the occasional 2-4 page reminder of the existence of other ways to handle this "good sound" business. That being said, people would do better to help out the newbie posts rather than hop into the Schiit thread.
I feel like I would get permabanned for telling a newcomer the truth about bias and pricing and snake oil here to be honest. Which sucks.
I wouldn't feel safe introducing someone unless I said the generic "Welcome to head-fi, start out with this dac/amp for your low impedance headphones and also sorry about your wallet."
