I'm a fan of DIY cables. I think you can build quality cables if you use high quality raw materials, careful construction including high pressure crimping of connections, and good design.
That said, building a speaker cable using cheap copper wire and then adding inductance and capacitance and soldering the connections fails on all counts.
