I think folks only get that way if a post seems critical of the higher end instrument as a result of these comparisons... or maybe more to the point, the purchasers of them.
I mean, I still prefer the Sadowsky, and even by a fair margin... it plays better, sounds better, is lighter weight, yadda yadda yadda. Is it 4x better? That's the HIGHLY subjective part. To some, yes, to others, no, but to those that the answer is "yes", they just don't like to read a post that seems to say they were stupid for feeling that way and spending the extra money.
Not referring to any particular readers or posters (truly!), just sayin' that's how that stuff happens... seen it a zillion times here... often innocently too, which is the unfortunate part.
