Property me two packets (100 meters) of cable ordered after (5 mm² CCA cable 2x1,) I was not satisfied with the sound in my home theater with the original cables. For the AV receiver performance and the established front speakers the sound was just too thin. By switching on the 2.5 mm² OFC cable I reached a significant increase in bass and sound characteristics of tower speaker (Celestion F30) in stereo mode. Overall, the whole surround mode sounds also stronger and more balanced. Applying the cable is excellent, a line is marked blue to distinguish, in addition, the cable can be easily unravel. Can only recommend for the price this cable.
