1.5 meter length of 1 year old Ethernet cable. The difference in these cables is that they 1) are Cat7 cables, per AudioQuest and 2), they contain 1.25% Silver Plated Copper conductors. Can you hear these over Blue Jeans ethernet cables, which they replaced. Yep, somewhat subtle but clearly there, particularly in the higher reaches where there was more sparkle and clarity. YMMV. I moved so new config changed my needs. Still have two of these in place.
