I have four 2.5mm balanced cables, two with MMCX termination, two with two-pin 0.78mm termination. The three copper ones are brands we don't mention on head-fi, but are sold on Amazon. There are both 8 core and 6 core two-pin cables. The MMCX copper cable is 8 core. These three were all purchased within the last two months and recentlyreplaced by cables from SG Audiohive and Trident, so I no longer need them.
The silver-plated copped cable is a Null Audio Ethos 5N cable. It's two years old, but has sat in a drawer for the last year.
None of these was super expensive to begin with (the Ethos as 59 USD and the most expensive of the bunch).
So here's the deal: $10 plus shipping for anyone of the bunch. I will ship to the US only using USPS first-class mail to keep shipping as cheap as possible.
