After a somewhat limited way, (I admit), I must develop the back of my mind. - Nothing to say next performances, videos and games go smoothly. Same for 3D (LG BD players, PS3 or Xtreamer - Multimedia enclosure - XTREAMER SideWinder III - USB 3.0 and HDMI multimedia box 1.4a + WiFi Antenna) Yamaha amp and Samsung plasma TV). - No interference, the cable is rolled up or used completely unwound. - The length (7.6 m announced unaudited) should allow you to connect your amp to a video projector in a room of medium size. (There are longer cables if needed). >> Two weak points: - The cable is relatively rigid and does not allow too tight bends. - The cable is quite heavy (at the base is a good sign in this area) These two points may be troublesome for the insertion of the cable into a PVC duct >> In the end, a cable not to buy lightly without being sure that the length suits you, but you will be satisfied once in place.
