Cable burn-in questions.

While burning in an interconnect cable, say the analogue output from a dac into a preamp, is it necessary for the preamp to be turned on? (I understand the answer would be “yes” if that input has not been used - to “break in” those circuits in the preamp.  But this question is focused on the cable.) Is current flowing through a cable when the preamp isn’t on?  Any reason why the amp connected to the preamp output must be on?  Does the volume on the preamp matter when a cable being burned in is connected to an input? 

  I assume speaker cables would need current and voltage passing through, to be burned in.  Does the volume setting matter?

    explanations for answers will be appreciated.

Volume from the pre does not matter but I don’t think the circuit is completed if the preamp/ amp is turned off (depends on how it is wired). If you are handy it is easy to make a dummy load with a spare RCA plug from your junk bin and a couple resistors.

The bigger question is if you can really burn in an interconnect with a DAC. Any idea of the output voltage? If it is a lot lower than a CD line level output it will take forever. It not enough power to do anything.

For interconnects you can make a simple DIY cable cooker. Make an adapter so you can hook up your interconnects from the amp to the speakers. Then play it at low volume ~40-50 dB’s overnight to a couple days. You will put more energy thru them in one night than having them in your system for weeks.


Just don’t crank it to max volume or you can fry a small gauge interconnect, they are not speaker cables.

If you have a multimeter check the resistance of the preamp input.    On and off.   If it is around 10K ohms you are good to go.
Again,  it depends on how the pre is wired.   Some can complete the circuit with the power off.   You probably will have to set the preamp selector for the correct position though.
