After numerous searches not really getting anywhere I thought I would start a thread and ask a few questions. I am currently choosing between 3 of the Forza cables for the AKG K812 headphones and wondering if anyone has any comments on the differences between the Forza Noir HPC Mk2, Claire Hybrid and Noir Hybrid cables? I did wonder about having the K812's modded for dual cable inputs, but not really sure I want to go to that kind of expense without knowing for sure that it would be a worthwhile change. Any done this and got any advice or comments? Has anyone changed the ear pads on the K812 to something other than the pads made for them? I found an old link on google where someone had used the velour pads from the Audio Technica AD2000X. But to do that you have to remove the plastic ring from a stock pair of the AKG pads to stick on to the AT pads. It's not that I don't like the stock pads, as they are very comfy, but it would be interesting to try some different materials to hear what effect it may have on the sound. I'd like to hear about some options if any one has any suggestions.
