Regarding the phono cable, if perchance your EVO III cartridge is the high output version you will want to keep in mind the following statement in the cartridge’s manual:
Note: If your receiver or pre-amp has capacitance loading capabilities, a Sumiko high output moving coil cartridges should be loaded with a value no higher than 200pf, and ideally below 100pf.
According to a review I’ve seen in "Soundstage" the Thor TA-3000 phono stage (if that is the model you are using) does indeed provide a selection of four different load capacitance settings.
You would presumably want to use the lowest of those four settings, if I’m correctly assuming that the numbers in their statement refer to the total of wiring capacitance plus phono stage input capacitance. But given that the tonearm cable and the connectors that are involved will probably present a load capacitance in the area of 20 or 30 pf or so, keeping the wiring capacitance in itself in the area of 100 pf will not be possible with many phono cables. ***And that has no particular correlation with price.*** For example, the Purist Genesis phono cable has a capacitance of 45 pf per foot, while the far less expensive Signal Cable Silver Resolution phono cable is 18.9 pf per foot.
If your EVO III is the low output version, though, while cable capacitance would be considerably less important, minimizing it would still be preferable. See the information provided by Lyra cartridge designer Jonathan Carr that is quoted at
this link, which is based on test results with a low output moving coil cartridge having the same output voltage rating as the low output version of the EVO III. And note the conclusion:
Comparing the simulations of the 3 cables shows that higher capacitances in the tonearm-to-phono stage interconnect cable demand lower resistor values at the phono stage input to control the resonant high frequency peaks. This in turn reduces the cartridge’s dynamics and resolution, and can also worsen tracking ability.
Good luck. Regards,
