Thank you guys for the responses. Mine is the new chassis, which has two small buttons to change input channel. It is the same as the new NFB8 chassis .shown on audio-gd site . My mistake to choose the new chassis, I probably have to return it.
Just saw on the audio gd website. with improved analog part, same EIGHT pieces of PCM1704.
Thank you Kingwa for bring it back and make it better. will order on monday. actually I just canceled the order for NFB8 wm. couldnt be happier.
