Here is more then you would ever need to know about audio cabling with speaker cable you prioritize reducing resistance then capacitance and inductance come into play because the low impedance high level signal with interconnect cable you first prioritize shielding then capacitance and inductance but resistance is basically irrelevant because it is a high impedance low level signal you want the lowest numbers for these factors to get better cable so here are the numbers: Cable Test 10khz Interconnects BJC LC-1 3ft cap: 44pf ind: 0.62uH ohm: 0.589 AR master series 6ft cap: 160pf ind: 1.5uH ohm: 0.15 AR performance series 3ft cap: 90pf Ind: 0.75uH ohm: 0.117 AR master series comp 3ft cap: 63pf Ind: 0.4uH ohm:0.030 AR master series comp 6ft cap: 113pf Ind: 0.7uH ohm: 0.049 Wireworld Luna 1.5ft cap: 145pF ind: 0.3uH ohm: 0.116 Wireworld solstice 1.5ft cap:160pF ind: 0.28uH ohm: 0.107 Audioquest Chicago 1.5ft cap: 64.5pF ind: 0.46uH ohm: 0.058 Monster 300mk2 3ft cap: 114pF ind: 0.86uH ohm: 0.121 Belkin pureav blue 3ft cap: 120pF ind: 0.76uH ohm: 0.16 Monster m1000comp DIY 1ft cap: 30pf ind: 0.26uH ohm: 0.021 Monster m1000comp 4ft cap: 71pf ind: 0.56uH ohm: 0.035 Mogamj 2534 2ft cap: 110pF ind: 0.29uH ohm: 0.043 Cable Test 10khz Speaker Cable Auvio 12-2 7ft cap: 115pf ind 1.6uH ohm: 0.024 NVX 12-2 7ft cap: 135pf ind: 1.45 uH ohm: 0.023 Knukonceptz 10-2 clear BFA 6ft cap: 152pf ind: 1.22uH ohm: 0.014 Knukonceptz 10-2 blue 3ft cap: 60pf ind: 0.59uH ohm: 0.005 Stinger 10-2 4ft cap: 73pf ind: 0.71uH ohm: 0.006 Monster xp 16-2 8ft cap: 118pf ind:1.77uH ohm: 0.076 Belden 10-2 6ft cap: 142pf ind: 0.88uH ohm: 0.01 These test were done with the DE5000 LCR meter in the picture they are performed by first laying the cable flat and touching the positive and negative contacts to the meter with the otherside open for capacitance and then keep meter in same position and short other end of cable for inductance and resistance shielding on most upgraded cables is immune to hiss and hum only really cheap cables have these issues unless you run your RCAs close to power wires or radio equitment but in most cases double shielding with a copper braid and foil is all that's needed I also have an audiophile USB cable here the science behind that is high capacitance and inductance on power low resistance then low capacitance inductance and resistance for signal to filter noise from the power give good ground continuity and not mess with signal the specs are here: USB cable 100khz Wireworld ultraviolet 3ft cap: 46pf signal ind: 0.8uH signal ohm: 0.206 signal cap: 336pF power ind: 0.258uH power ohm: 0.15 power Belkin Gold 6ft cap: 93pF signal ind: 1.4uH signal ohm: 0.85 signal cap: 254pF power ind: 1.0uH power ohm: 0.2 power And for power cables just have 14 awg or higher and shielded so noise does not get into other cables I use belden 83803 but generics are really fine here And for hdmi cables just get the current version the TMDS signaling in them makes the cable switches and couplers irrelevant to quality they work or they don't Overall speaker and RCA cables are the most important to quality power USB and hdmi are more then likely not audible component composite or s video cables do make a difference the same way interconnects are effected but those are hardly used in modern equipment
