We have connected this cable to an AV Receiver Onkyo HT-R558, and Wharfedale Diamond 9.1. The sound is transmitted clean and balanced ... where we could test also much more expensive Oelbach cable but I ...... could not tell the difference in sound ... Of course, a CCA cable can with a rather low percentage of copper conductivity and thus no transmission qualities of pure copper cable have (CU), and this cable is also no high-end listening enjoyment Spezi satisfy ....... but we are talking about "here indeed of an 8-Euro cable) 10.Meter audio cable with a thickness of at least 2.5 mm² for 7.77 euros which is top ..... this strength is the way optimal for our AV receiver .... we are satisfied;) Greeting Mike
