While Copper Clad Aluminium (CCA) Ethernet cables are in some cases a third of the price of Copper cables, there is still this unsolved dilemma - Which cable is good for what and from what point do you decide which cable to go for? I have searched on here and through the internet, found a few articles that state people should avoid CCA cables like the plague, others said it's OK but not for intensive purposes, while others said that you might experience problems with HDMI... From what I understand (from online articles) is that CCA has a higher packet loss rate due to the small amounts of copper smeared on the aluminium strands, therefore while data applications can put up with lost/corrupt packets on the way, video will be more sensitive to it and one will experience undesired side effects. But is this "video", video of a 1080p resolution being streamed to 4 TVs in the house simultaneously or even simply streaming Youtube 1080p to one PC that one will be experiencing problems? Will you experience problems streaming 5GB MKV video file and transferring large files simultaneously on CCA rather than copper? Have any of you installed CCA cabling and noticed any drops in performance, quality or an increase in packets loss?
