To piggyback onto this - what do you all use for headphones?
I currently have a non-headphone jack model FM3, and I'm running it through a Presonus iTwo audio interface with their HD7 headphones plugged into its' headphone jack, and it's the same, yucky, tinny, high-end'y headphone experience that many of us are familiar with. I know that in the strictest sense, using headphones will likely never completely sound ANYTHING like it does through an FRFR cabinet - that's hard to replicate, to say the least.
That said, though, is it possible to use a headphone set up that's at least somewhat close? I have my eye on Beyerdynamic DT-880 Edition's (250ohm version), but I want to know if it's even worth trying to pursue.
I'd love to hear your thoughts.
