Zunächs: I can not connect my speakers, when it comes to the flexibility of the cable.
I feel it is soft, flexible and with the mentioned 7mm diameter than thin.
I have my orders the HDMI cable to a Sanyo PLV-Z800 Sanyo PLV-Z800 LCD home theater projector (Contrast 10,000: 1, 1200 ANSI lumens, 1920 x 1080 pixels) white / gray with a VU + Duo VU + Duo Twin Linux HDTV Receiver ( CI slot, Conax card reader, HDMI, 3x USB 2.0, 1080i upscaler, 2x Scart) or PC in order to connect BluRay. The cable is located along with other cables (2x satellite, 1x network, 1x YUV, 1x electricity) 7m parallel 25x25mm in a cable duct and makes no problems!
I have at max. May find resolution of 1080p (BluRay Avatar) no artifacts.
I can now only recommend the HDMI cable.
Best regards
Martin Link
