Astro A40 - HD555 mod
Swapped out the A40 drivers in favor of some Senn HD555 drivers. Rewired the right side driver and mic using an unbroken quad mic cable, eliminating the pcb break points in each arm. Detachable cable has been upgraded in favor of Lemo pushpull connnectors. cable is terminated to a 4 pin mini xlr and short 1 foot adapter terminated to a trrs 4 pole plug for astro mixamp use. Custom paint job is primarily black with metallic burnt orange highlighting. driver holders are charcoal pearl and everything is finished with a urethane gloss clear coat.
results... huge upgrade in sound and overall look.
