This is my first DAC. Was choosing between Loxjie D30 and Topping DX3 Pro V2 to swim into the river of hi-res music. Connected via Toslink to UltaHD sat receiver for Mezzo HD music and via Bluetooth to stream from my iPhone. Sennheiser RS180 (uses Kleer technology) connected to Topping DX3 Pro. Now I can move over the home and listen to my favorite songs.
