You can see in my sig where they'd be going[replacing HD650s which are amped]. I fancy 'em cos they're closed and does low impedance mean they're easily-driven?

My D5000 is driven by iBasso D10 with love!

Yes they are easily driven and sound great already plugged-in the headphones out of my iMac, but they will arguably sound better with a dedicated headphones amp like the X-Can for instance.
I say 'arguably' because it isn't always noticable.
