I have been using my system that I use in Computer Source with Fiio K7 Dac for a long time with satisfaction, while looking at used products on sale from time to time, I found a very clean boxed D50 whose screen light did not work and I bought it for 50 Dollars (2kTL) I can say it is free. and the sound is really great. Fiio has a price of 10-12K TL and I have reached a great setup. Win11 USB Connects Without Connecting It recognized it in seconds and set it as 32bit. I installed it right next to the USB input of my DRA800. I got rid of the cable plug crowd and I am in savings of about 300 Dollars. everything is great
