Good and cheap cables

I had in the living room a smorgasbord of HDMI cables in use and had always had problems with stuttering, pictures and sound, especially often when watching Blu-ray movies.
I use a Denon AV receiver via all devices (Samsung TV, Samsung Blu-Ray, HD Receiver Technisat Isio and the Microsoft XBox are connected. With the old cables were always problems and I could not locate whether these problems of a certain cable caused. I then bought a pretty expensive Oelbach cable and exchanged in this circle to see if possibly generated a particular cable a bottleneck. As my TV set is mounted on the wall, I suspected that maybe by kinking the cable to the TV, the problem could have occurred, but in the end came the error with images and sounds over and over again and bugged.

Then I bought at Amazon for the television, this cable with right angle plug and bought another short 0.5m cord of the same brand for connecting other devices to the AV receiver and connected everything about it.

Now is peace and everything is working at all times exactly as it should.
