Help selecting a power cord.

The Puritan PSM 156 is Outstanding and the best I've tried in my system and have owned many...

Power cords don’t make much difference in my system because of the components.

I cannot tell whether you are implying your system is too good or not good enough to benefit from cables. (looks like a very nice setup to me) But either way, I would suggest you try one really good cable on your power amp and then make the call.

I found power cords made a bigger impact on my system than either ICs or SCs. What goes down your speaker cables is sourced from the mains. The input signal dies at your first amplification stage. The cleaner the AC that enters your amp, the better your sound.

You’ve spent money on your system, don’t keep it back by cheaping out on PC’s.

When I tweak amps, I always spend most of my effort and resources on ripple/noise filtering on the power supply. I’ve always found that to be the best bang-for-buck. A good PC enhances your amplifier's power supply ability to produce a more ripple and noise free DC supply, whether you have a budget system or a cost no object system.

I'm happy with Pangea. The high end cords didn't sound any better (not sure of the brand).  I sold them for shipping cost to get them out of the house quickly.

LOL. I roll cables like I roll tubes. Ditto for capacitors. It's not like I'm unhappy with my sound, but I cannot help myself trying out something new. I think if I ever stumble on the "perfect sound" it will ruin the hobby for me!

I guess even in a rather exclusive group such as audiophiles, there are a wide range of different personalities with wildly differing goals and opinions. 

Anyway, I'm glad you found your sweet spot ... and I'm glad I haven't found mine.

Very well said. I agree.
