This is someone's modded AK100 given to me asking to improve it in a way better than improper mod of by-passing resistor alone. I made some franken adaptors for small tests while waiting for real deal. My theory turned out to be right and thankfully that Dr. Jan Meier already pointed some hints about this out way before I have my hands on AK100 so kudos to him as well. I'd have left this alone like him if no one dared to give me one for free to mod this :D
Ears dont lie...audibly speaking the mod is very recognizable improvmement...now I cant speak to the technical aspect of it...re: if the unit melts out in a month of heavy high volume etc. I have been using the RWAK with my HD800's via the RS Intruder...SQ is better than some of the full size systems I've heard via my HD800's.
