Headphoneus Supremus
I recently re-cabled a Pro4AAA for the first time. I think there is a difference but it's hard to gauge because I have to adjust the placement of the original pads on my ears. There is a boost to the sound but that is all I can say at this point.
Old wires get corroded and oxidized over time, and in cases of low impedance headphones it's very possible to hear noticeable differences when they're replaced. The 4AAA used poor wires, but it had high impedance transducers so the only thing you should be noticing is more volume.
