Audio-Technica RCA Cable FINE GOLD 0.5m Pair Blue audio cable using gold-plated RCA connectors. - Connector Type: RCA connector - Number of Cables: 2 - Connector Material: Gold-plated - Color: Blue I am selling this because I upgraded my cables. The appearance shows considerable aging, but when compared to the new cables, I couldn't tell the difference from cables costing around 10,000 yen. When compared to 6N and 7N cables costing over 20,000 yen, there was a difference in the bass response, but I was surprised that there was no difference in the treble. The comparison was with 1m cables, so the length may have been an advantage. Thank you for looking.
