I'm not sure my sources were enough to scale Plus5 at the levels you guys are hearing them. Seems those who get the most from them are using top-tier players. I never did try them with the Tralucent DAC though which is quite nice regardless.
Up for sale is one pair of Fidue A83.
I have owned these A83 a while, they have brought me many excellent listening sessions. Like anything in this hobby I've upgraded and they're no longer used much. They're great condition and come with their original box and all accessories.
Any questions please send a message.
