Although, it also effects a change in gain as a side effect of the impedence change, there is of course, a high and low gain selector for that purpose.

Indeed in my testing with my cans listed,when the "low z" jack is utilized, there is a relative increase of control over the drivers effecting a tighter more accurate precise presentation to the music being played .
Also, I have great hopes of experimenting with my already moded k-501s, to be recabled hardwired to each driver each with its own termination to plug into both seperate low "z jacks", as a frankinphone pseudo balanced experiment.
