I replaced a mixture of old generation Isotek, and some other well regarded manufacturers power cables with DIY. Oyaide black mamba v2 with furutech plugs and oyaide IECs (c-004). Very surprising uplift in SQ on my digital sources and Lyngdorf TDAI3400.
its a very very rigid cable which is difficult to work with but get the lengths right and you can keep the cables suspended relatively easily. I think that helps with vibration control. I also used FO.q ta 102 and ta 32 damping tape on the cable grips and other parts of the plugs and iec. Also using total contact contact enhancer (no longer available) but you can get other offerings from furutech, oyaide walker audio and others. Well worth going this extra mile.
