I'm getting marvellous results from a pair of homebrew interconnects between DAC and amp following Greg Weaver's SST article. The IC I built uses copper magnet wire (0.02 mm^2/~34 AWG), 38mm wide tape (Tesa 4124 clear) with about 30mm spacing between the parallel wires. Using narrower tape than what the original recipe prescribes may be a step in the right direction toward getting an elegant termination - the only difficulty with this design. I would love to hear from anyone who was pleased with flatline / ribbon / tape cable cooking or found, comparatively, other geometries significantly better.
