I had my 5.1 speakers with 1 x 17 mtr., 1 x 15 mtr., 1 x 9 Mtr., 1 x 5 mtr. And 1 x 2 mtr. Connect speaker cables. Only a 15mm cable conduit I wanted (use for optical reasons for 3 speaker cable, 1 Chichkabel (subwoofer), 1 x data cable Unitymedia, only 0.75 mm cross-section out of the question. For my hearing and my `` Musikgefühl`` is the Quality perfectly adequate, I can compare, since the plant previously communicated 2.5mm and 1.5mm was wired. I have not discovered an audible difference. I would buy the cable immediately! Ordering, payment and delivery process properly and as expected.
