Tubulus Argentus i2s Cable

Very neutral and detailed i2s cable, with a realistic, transparent, open and width stereo image!

Review Quote:”…The music gains in detail and it sounds spotlessly clean. There is lots of space making the stage wide and deep combined with a beautiful powerful and layered middle area. The improvements ensure increased involvement and you are dragged into the music. You get the feeling that nothing is getting in the way of the music, as if there is no cable at all…”
