The only thing I've really ever flopped between was my evaluation of whether the SRH940 or HD650 was more "truly" detailed early on before I gave the SRH940 more head time. The reason for this was that the HD650 is really quite laid back, and the SRH940 has super detailed highs -- a confusing contrast. I was flip flopping between trebly and bassy music, in which case different ones will win out here.
I've since learned a lot about frequency response and my ear is a bit more trained: I've been saying the same thing about the SRH940 again and again for months now: The SRH940 treble detail beats pretty much everything in the price range, but the bass and mids are just "okay". Also the SRH940 is less natural in tonality than HD650, but can sound more realistic due to the added detail. Again, I've said these for a while and I still have no reason to change my mind so far.
Anyway don't take what I'm saying about the HD800 to mean the SRH940 has just "okay" treble. The SRH940 has incredible treble. The HD800 treble is just twice again as good, and the mids and lows aren't even worth comparing.
