I agree with that sentiment. It took me just over six months of comparing cables to find what works for me with my electronics and my music in my room.
So nobody else could advice me. I tried many and ended up with Cardas Golden Reference IC and Speakercables and Kimber PK 10 and PK 14 Palladian Power cords.And yes I did blind listening tests (a friend swapped cables for me).
It's also true that this not inconsiderable expense would be false economy on a budget set up.
