These are only 14 months old and had great results. I’m downsizing my system to an integrated amp which will require longer speaker cables. I plan to order a long run Iconoclast SPTPC Speaker Cables.
Both are listed on US Audio Mart, links below to ads.
1 pair of SPTPC Speaker Cables with Large Spades - 6 feet
1 pair of OFE 4x4 XLR Cables 15 feet
