Thank you very much, Kevin, for a good info.no soldering. just flip the switch.
Since you have already replied here, please tell me another thing. At present I have two Stax headphones: SR-L700MK2 and SR-009S.
I need to sell one of them. Which ones are best left to work with KGST, i.e., which headphones will I have more fun with if I pair them with KGST?
Thank you.
