I also had the stock and alo mod vampire cable to compare and alo mod was right from the start with no burn in smoother and less harsh and only got better with burn in.
for me the stock 780's were too bright and fatigued my ears but not the alo mod.
I just sent my stock version to get recabled with mogami cable and have the diodes taken out. I will compare that to my alo mod when I get it back soon.
