Hi capacitance wires normally sound very good with high current solid state, but can cause a few problems with speaker phase angles and tubes just don't like it. The cat 5 example above is a very high capacitance design.
SOTA diy speaker cables
It would be great to have diy cable and interconnect formulas to compare with the high dollar ones promoted here. Not in an effort to 'debunk the myth', but to make available high performance for those of us who may not otherwise have the means to take advantage of current technology in an inflated marketplace. Has anyone put together anything worthwhile to share?
