After market cables can be quite polarizing. While I don't notice a huge difference, others might do. I went with the SW due to its looks, and to make me less shallow, the craftsmanship and overall build quality. Values it shares with the K10 I've not heard other TOTL CIEMS. The K10 was my first CIEM and a big jump into the unknown. Luckily, I struck gold and even after 4-5 months I've no desire to upgrade.
