I have Cayin C9 in as new condition for sale. No signs of use, plastic screen protector on the new glass. There is another spare one in the box. The unit has about 1.5 year of use, works flawlessly and tubes were rarely used. About two months ago I’ve bought the case for 90€ from cayin in China. I also have a custom cable RCA to 3.5mm OCC copper 6 litz. I was using it between the C9 and hugo2. Can include it for 80€ extra

Best wishes,
Kajetan
