You do not have to "suffer listening" during the break-in period. Since the cables are connected ahead of the power amp, the amplifier does not have to be turned on. You will have to suffer changing or restarting the records. If you have a tuner or cd player that can do repeat play that could do for the pre to power amp cables. You will have set the volume level to your normal setting or maybe slightly above.
I understand that you replace both phono in and pre out at the same time. After the break-in, I suggest replacing just one set with your Audioquest cables. Possibly choose the best combination for your likings.
However, my experience with breaking-in cables. They are very subtle. I don't think Hideous to Glorious will be realized,
