Interconnect Cable Length


Quick question - I have a preamp with 75 ohm output impedance and an amp with 47K ohm input impedance. What would be the maximum length of interconnects I could use between them without sacrificing sound quality? I know the answer will depend on the quality of the interconnects but I'm trying to work within a $200 budget, if at all possible. For example, I see the AudioQuest  Evergreen cables sell for ~$120 for a 12 meter length. Also, is there a general rule of thumb for trade off between speaker cable length and interconnect length, assuming comparable quality cables?

Thanks in advance.

With 47K input impedance, there should be no problem.
Your total active resistance will still be within tolerable single digits of ohm if not less.
Going silver is far more pricey, but active resistance nearly halves vs. copper.

I'm sure you're not the first heard by me who didn't feel any difference between hi-end and low-end cable or longer vs. shorter one.
