most of the grado models have impedance value of 32ohm (pretty low) and sensetivity value of 98db which is also considered very low in the headphone world. so what is the logic about them being very easy to drive?
One reason for the Grado reputation of being easy to drive is that the sound doesn't change that much between unamped (iPod) and amped (a reasonable head-fi level amp). At least with my SR60 the unamped and amped sound is very similar. Higher end Grados may be different about that though. I don't have enough experience with higher end Grados to know. I just recently got my SR325is and haven't even bothered to try it straight from the iPod yet. I've never even heard an RS1 yet.
I sometimes use my SR60 with the iPod. But it's a drain on the battery. Usually I use my Senn PX100 with the iPod. The PX100 is much more efficient than the Grado and less of a drain on the battery.
