I was wondering, are there any stores in NYC where I can demo any of the Hifiman cans?

Do the HE-500s have more pronounced treble than the 598s?

I guess I'm asking for your individual opinions then. Perhaps I could have phrased that better. When I listen to the 598s immediately after listening to something like the B&W P7, I can immediately discern how much more out of the head the 598s are. I guess what I'm asking is, if I were to...

Given that the hd650s have a smaller soundstage compared to the 598s, would it be possible to give a percentage estimate of how much smaller it is?

How hefty exactly of an amp do these require? I own an Audioquest Dragonfly ... is this insufficient for laptop use?

  Looking forward to your review! :) What would you say would be your favorite of all 6?

Do the M200s benefit from being ampped, say with something like the Fiio E17?

Interesting ... what about the FX700 versus the M200? It's interesting because you find the M200 to be overall more refined than the DN-1000, so I'd be curious to see whether you find that to be true for the FX700 as well.   Also, how does isolation compare between these three? 

For those who have heard both, how would the DN-1000's sound quality compare to that of the JVC FX700?

Is there an IEM that has similar musical qualities and overall perceived bass quantities as the Yamaha EPH-100, but with more sub-bass and slightly less mid-bass?

Would an M50 be a reasonable headphone alternative to the FX700? If so, what would be a main differences in sound?

How would these compare to the FXT90s or the CC51s? It seems to have a similar sound signature to the FXT90s and a similar microdriver design to the CC51.
