In before TOS listens to cables. I will be the first to say this should not be a high priority, but I think it could be interesting to see how much of a difference cables actually or really make subjectively for each tester. SBAF has never struck me as a nervosa "I might miss out if I don't try all the tubes and cables type of site" but this is actually why I would prefer something like this to be tested at SBAF (assuming people care enough to even take the time). It could be between different RCA, XLR, SPDIF, Coax, USB, headphone cables, power cables, different wiring on a home made amp, whatever else, etc. Between different mfg or maybe different product lines by the same mfg, different lengths of the same cable, cheap vs expensive, 2 identical cables but one has cryo or some kind of magic pixie dust treatment applied, etc. Maybe: Note or artificially create noisy vs clean environments (electronically), hot vs cold, whatever other variables. Have someone here good at measurements measure the different traits of various cables but not reveal measurements until end of loaner and see if particular measurements correlate with particular results once everyone is done. Measurements could be however much or little, could be a quick R or C measurement or a cable, a more complex Z (impedance) measurement over various frequencies (I know, small differen, or measurer could go crazy with some grad level EM theory regar/speed of electrons/how sunny is the sun type stuff.
