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.
