i disagree about the 32ohm 770s.
they have a good amount of bass, about on par with my 600 ohm 990s(a lot more sub bass but less mid bass than the 990s) and are pretty avg without amping.
i think the pro 80s sound better unamped than the 32 ohm premiums.
but the 32s will get a tiny bit louder
i'd like to edit this above information with the disclaimer that my portable music player is WEAK.
so maybe i was really selling the 32 ohm version short.
but i still never found them bass light at all.
not on the same level as the pro 80s
but far from bass light to me
whats the formula for vrms?
if you have mW and output impedance what do you do with em to calculate?
