Can you please explain why such low impedence is important? x2 are 30ohm, why wouldn't an amp rated as low as 10ohm be suitable?
Well, the rule of thumb is that the output impedance of the amp ought to be at most 1/8 of the impedance of the headphone.
The X2 has about 32 ohm impedance 32 / 8 = 4 therefore the amp powering the X2s ought to have an output impedance of 4 ohm or less.
Why the rule is the way it is you'll have to find some source better than myself.
