??? Full Loom vs Mix ???

On my system a full loom of power cables and IC’s has been very nice. USB and preamp umbilical cord another maker.  I look for cables that are neutral, don’t color the sound and let the components sound come through and shine.  So far so good but cables are a long and twisted rabbit hole.  Good luck with your quest.

I have all Analysis Plus IC, PC by LessLoss and Speaker Cable is Townshend Ribbon Isolda EDCT speaker cable. Fantastic sounding system.

To bear the fruit, you need the full loom. 

You can try either method. Both work, and yield different results you might like. The wiring in your components is not all the same now - it’s already intermixed. While I’m back to running a full loom of Cardas now, end to end from source, digital, for all components all the way to the and inside my speakers - I have intermixed a lot. Intermixing the best from Cardas purist copper, Analysis Plus OCC, Aperture Silver, Audioquest, and others with nice results. Some actually prefer intermixed cabling over one brand/level end to end. Try both methods if you can.

You might also land on an intermixed cabling setup that you like more for your system, your room, and your ears. 

@mapman - good one
