I ordered the AUDIOPHONICS PSU-HC Linear Regulated Power Supply 12V 5A 100VA as a replacement for the switched-mode power supply of my FRITZ! Box Cable. Fast delivery. The power supply is very heavy and looks extremely high quality. It works perfectly with my FRITZ! Box Cable. Highly recommended. I struggled a little to get a DC cable. The ordered cable with 2.1 mm pin did fit into the power supply unit, but not into the FRITZ! Box. An adapter from 2.1mm to 2.5mm solved the problem. Everyone who is on the move when it comes to sound and reliability: an absolute recommendation for the FRITZ! Box Cable. Very good product. I also have a 5 volt linear power supply from Audiophonics for supplying a primary streaming bridge. Also very good product. The boys know what they're doing. Thank you.
