Hello All,

What is an acceptable difference in dc resistance between the channels in a pair of Grado SR-325s?

One channel on mine measure 33 Ohms, while the other channel measures 35 Ohms. Should I be concerned?

Maybe others could post the numbers from thier cans...

Thanks,
Bryan

Just for reference I measured two high impedance phones.

AKG-K141M: 669 Ohms both channels.

Beyerdynamic DT-880: 570 and 556 Ohms.

I thought the drivers were supposed to be matched. Does db matching directly correlate with impedance? Some Grado users do complain about their phones sounding shifted to the left or right.

DC resistance is just that, resistance at DC. Might not correlate at all with the impedance at audio frequencies.

You are right with the statement,  but do you expect two drivers with quite different dc resistance to perform consistent in AC domain?
