What's the output impedance of the headphone jack? That's a crucial thing to know.

thefitz NX2s use TI's PCM5101A and output impedance of headphone amp is 3.3ohm.
Found that myself. 3.3 ohms is a lot for some multi-driver BA units.

thefitzWhere did you find this info? I'm trying to determine if the NX4 uses the same DAC.
EDIT: NM, I found the Head-Fi thread.

SythrixWhile I copied a post from head-fi, the person who I'm copying got the info directly from Topping tech support.
