Selling this DAC/Headphone amp/Pré-AMP bought it 2017/Nov directly from nt-global in Germany https://www.questyle.com/en/product/CMA400i Full functional and in mint condition, no scratches or other visible marks. I don´t have already the original box, one of the pictures shows a DIY acrylic top. Selling since I'm not already using it. Got it to interface my DAP with my home system and as a HP amp, later discovered my CD Player has a SPDIF input. Price includes shipping registered airmail for Europe.
