If you had only ONE aftermarket/quality power cord where would you place it in the chain ..1/source(CD player)..2/preamp...3/power amp..4/from wall to power supply..and why?..Please no "try them and see what sounds best"...thanks

I would try it on all your components and decide where it works the best. If you don't hear a significant improvement somewhere, you don't need it.
In my situation, using all Lessloss power cables, my preamp/dac provided a better place to put the pc, than the APL Denon 3910 that I use as a transport. But it wasn't until I added two pc's to my Nuforce 8.5's(version 1), that a synergy occurred.
