Is there any rule of thumb as to what component will benefit most from After Market Power Cables? If you have cords of varying value/performance, what component should you place your best cable on? I have been reading that Source (CD Player) is where you see the most benefit, but would like more feedback from AS members. Also, is larger gauge as important for Amps, or is 14 good enough? I also use an APC H15 for my main 2 CH system which actually came with the most robust 12G cord of any component I have purchased. Right now I have a Pangea AC14 SE MKII on each of my Pre Amp and CDP and a PS Audio AC3 on my Amp, all running thru my APC. I tried the Amp directly to dedicated outlet but preferred thru the APC as my normal incoming house voltage is low and the APC ups it closer to the norm. On another forum, it was suggested that the best cable go to the APC. I am considering getting a few more but trying to decide if I need larger gauge going to the APC or if another PS Audio AC3 (12g) is good enough or if I should go to the Pangea AC9 (7g) cord to power the APC. I am also wondering if the Pangea AC14 SE MKII is good enough for my Pre Amp or if I should step that up to another PS Audio AC3. Thoughts, suggestions, experiences? And just for the record, after replacing the 3 stock 16 and 18g cords with the above, I have what sounds like an entirely new system, for the better. I am actually stunned by the benefits I got as they are far from subtle.
