Default Re: Audiophoolery. 'Cable Break In' - I never knew that!

I put the loading resistors for the 30 ohm in the jack plugs at the amplifier end of the cable.
No need to do that, volts out will stay the same, all the 30ohm means is what the minimum resistance it can drive. You could have saved a number of pennies on the cost (grin).

And being a bit silly (if this thread wasn't silly enough, great fun though)...

It is common practice to match a cable run at the destination
staying in the middle lane is also common practice, doesn't make it right.

Luckily today (for the last 40 years at least) we have audio stuff with low output impedance and high input impedance making cable irrelevant, even screening isn't required in most cases, just as well, the unbalanced unscreened twisted pair seems to have a following in the "interconnect" scene.

To top it all the RCA Phono "jack" is all pervading, quite a bad connector IMHO, OK it's more than good enough for audio and cheap, I use them because cables cost pennies and that saves loads of time soldering.

To sum up, it's bloomin' audio, nothing above 20kHz means anything (outside the box anyway), nearly DC as far as cables below a mile or so long are concerned. 20kHz is about 10 miles wavelength.
