Question about break-in method for interconnects


A dealer told me that an interconnect being broken in between a preamp and amp will only carry signal between the pre-amp and amp, and cycle the signal, if the amp is powered up and connected to speakers.

Others have told me that merely having the amp powered up is sufficient to have the signal cycle.

Still others have said that having the IC carrying signal to a turned-off amp is enough.

Perhaps it is component-dependent, but I would think that an interconnect running between a powered-up preamp and powered-up amp, whether the amp is connected to and driving speakers or not, is carrying signal and thus breaking in.

Which preamp / amp method described above works?

Thanks.

The amp provides a signal input termination whether it's powered on or not; that is all you need. Signal current flows thru the interconnect regardless of the amp being powered off or on. Never mind the speaker side termination which has nothing to do with the input & matters not in the least.
In Brian's above example, interconnects again will only pass signal current if a load termination is present at the end of that cable. If you are connected from an operating tuner to preamp, then the interconnect only has a termination if the preamp's 'tuner' input is selected. If any other source is selected then the cable has no termination, no signal current flows, no breakin is occuring.
