??? Full Loom vs Mix ???

I don’t use equipment from the same manufacturer

The wiring in your components is not all the same now 

Excellent points. 

As said by others...unless you can A-B test cables in a system, any use of memory is suspect to me. I think, I hope, most of us can agree synergy is a real thing in pairing pieces of equipment. I think it also exists in mixing cables. If synergy is real and exists amongst equipment, amongst cables, and the pairing of the two, and that is a big IF for some people, which is easier, finding synergy amongst various cable manufacturers AND various electronic manufacturers or in finding a full loom for electronics that themselves pair well together? I have an Aavik U-300 integrated paired with Raidho TD1.2's...it is pretty widely accepted these pair well...I'm sure many would say I should go with Ansuz cables but I can't afford it and I'm reluctant to put all my electronic/cable "eggs in one basket." So, I have a full loom of Audience Front Row and I feel it fits well with my system today and likely anything I would get in the future. I guess I'm a whole loom person who finds that easier than mix and matching while looking for synergy between cables and equipment. 

The manufacturer will of course tell you that for best results you should use their product throughout your system.  Heaven forbid that another brand gets in between theirs and prevent you from reaching audio nirvana.

Some really high end components include custom speaker cables, power cords, etc.  You should probably throw those away and get a full loom of something else.

As you may guess, I'm a bit of a cable skeptic.  Not in the sense that they are all the same, I can hear audible differences between cables. 

However, I would rather pick up good used cables at a heavily discounted price and piece together a system with high quality cables of different brands than to pay list price for a full loom of cables throughout my system. 

If you have the funds to do so, and it matters to you, I don't think it's a bad thing and certainly will look better than the mess of cables I have behind my system.

I have never had a full loom of any brand.  I let my ears do the talking when it comes to what I purchase. So a couple of years ago I, @blisshifi suggested I buy a Silver Sonic Mirage USB .  I did and it was really good.  A couple of months ago I tried a Clarus USB that retails for twice as much.  I went back and forth with it and the mirage and ended up sending it back.  So right now I have a Silver Sonic, some Clarus, an Audio Art and an AQ cable in my system.

Your equipment isn't made with the same internal cables, even if you use the same equipment brand. 

Your equipment may not have cables at all internally, sone very high end equipment commonly has only PC traces. 

There are different loads all equipment are designed with, the cables should be transparent making those loads exactly the same at the inputs and outputs.

RF negation is real but with quad interconnects and good ground and insulation it's not the problem it used to be. 

Line level signals next to power lines can change signals with low quality cables, but not good cables.

How does the cable manufacturer of very high end cables know exactly what interconnects/speaker cables you need unless it is tested in your system, answer, there is no way and if the cable does make a difference in the sound it is only negative a perfect cable will only make no difference in the signal.

Just go with what sounds good, don't get caught up in the silliness.
