Musin is Japans iBasso distributor.
Keep in mind this is heresay/rumors/whispers
but it would make sense to do an updated all in one DX160 style in a DX200/220 sized shell with Max/Amp8EX tuning.
The modules have shown clearly what people want (the most popular ones). So no need to continue that?
Hopefully there will be a DX320 for module users also.
