Hmm! I was just using caps as an example. I was referring to everything that goes into a final product.
Customers don't just buy a design but a finished product that is built from a group of SELECTED parts. Just the fact you chose solder, wire, transformer, cap, tube socket, fuse ... A over B, you are essentially voicing the final product.
I've spoken to many "competent" designers and they prefer point to point wiring in that it's easier to test different parts to archieve the desire sound.
