How much does volume matter when breaking in amps and cables?

I enjoy few things more than listening to a component as it burns in. The changes are just fascinating, especially the first few minutes to hours. Speakers, amps, cables, even fuses. Just one of the most amazing things, and I listen closely every time. In 20+ years I have heard no evidence volume matters at all.

Good grief are you fat or what?

Buy a  good breakin cd that uses a lot of sweep signals like the purist audio, or anther we’ll know CDs just play. On repeat or burn to your hard drive I have done this many times cut runin time 
by at least a 1/3 rd also shut off for a 1/2  at least 1-2 x a day 
for it discharges the. Capacitors  then you reenergige them 
it help with cap breakin . Being around audio almost 40 years 
have got a lot of good tips through electronic tech friends.

They’re not fat! They’re chunky. 

Volume is required to obtain sufficiently high voltage and current. Otherwise cables never break in. Duh!

I would have figured since cables need breaking in (plus, I've heard the rca/xlr connectors on the cables needs to break in as well), that one should "break-in" each input/output that will be used on a pre amp.
