Conditioning/Burn-In Method

Now, to business.

I'm in the process of working in a set of Signal Cable Silver Resolution XLR interconnects between my DAC, Preamp and Amplifier. So far, I probably have only 20 hours or so of play, and if memory serves, Frank recommends 60 hours or more. Given the difference in amplitude from DAC to Preamp, and from Preamp to Amplifier, do you guys think it might be worth swapping them out (rotating them) to help balance and perhaps accelerate the process?

Thanks in advance!

Perhaps I should add a disclaimer, but...

Why is it so odious to just let thing break in, in their own time.
Is 60, 200, 500 hours so long?
I have found that just listening and hearing small differences, sometimes big differences, to be very satisfying.

@gdnrbob   They say patience is a virtue.  You, sir, are more virtuous than most audiophiles I suspect.😇
I use an old iPod Nano (remember those?) as my break in source, playing a mixture of music, signal sweeps and white noise MP3s (XLO has one available for free download) on auto repeat for a week. If you have a FM tuner laying around that works too but I like being able to make a playlist of things. 

If you are reasonably handy you can terminate the cables with a load resistor around 100 ohms to get a lot more current through the cable. You don't even need to solder or use jacks, test leads with alligator clips will do. If I need more power I use a Dayton T-amp and a 4 ohm load resistor. This stuff is not that complicated and you do not need to buy any fancy discs or equipment...
Fair questions and points.

@gdnrbob, because I'm also breaking in the speaker cables, running at higher volumes for 10 or more hours a day just isn't possible, especially since I work from home.

@taww, I did set a play list of about 10 hours worth, and going with Elizabeth's suggestion, I'm running in the ICs, but I do need to also work on the speaker cables. Is the 100ohm resistor something I could pick up locally? Someone also suggested a 200watt light bulb... would that work?
I would not recommend using a 200 watt light bulb, and in general I would not recommend other light bulbs rated to operate at 120 volts.

Their resistance will vary extremely widely depending on how much voltage is applied to them. For example, a 120 volt bulb whose power consumption under normal operating conditions is 200 watts will have a resistance following its very brief initial warmup of about 72 ohms. However, extrapolating from resistance measurements I’ve performed in the past on various other light bulbs its resistance when cold will be in the rough vicinity of only 5 ohms. So depending on how much signal is applied to it by a power amp its resistance may be at any point in between, and its effectiveness may vary unpredictably.

More significantly, if you happen to be using a tube amp resistances in the higher end of that range may be too high to be safe. As you may be aware, tube amps which have output transformers should not be operated unloaded, at least when they are processing a signal, and 40 or 50 ohms or more may be high enough to be an inadequate load, that may result in serious damage.

And of course the 200 watt bulb would be totally unsuitable and quite possibly harmful if used as a load for a DAC or preamp, which would not be able to supply enough current or voltage to raise its resistance above the vicinity of 5 ohms or so. For that matter, operating DACs or preamps into a 100 ohm resistor for a considerable amount of time could conceivably not be healthy in some cases either, in addition to being extremely non-optimal sonically if the system is listened to while the resistor is in place.
