Yes, I have opened them up to swap opamps as previously posted in this thread. Simply unscrew the 4 screws on the top of the HP-A4 to open it.
After trying out many different opamps on the HP-A4, I've found the MUSES8920 to be simply the best sounding opamp for the HP-A4. At only 480 yen a pop, anyone who's looking to upgrade their HP-A4's sound quality should definitely get it. (it can be bought from Akizukidenshi via Tenso buying service)
i see, do you happen to have an extra piece?
i bought some muses01 from them previously
