Are upgraded power cables for subwoofers worth it?

I recently have been filling in all of the holes in my secondary system.  Recently picked up a shunyata power conditioner, upgraded speaker cables, and power cable for my amplifier.

My question is, is it worth running higher end audiophile power cables with subwoofers, considering distortion is not as apparent to the human ear in the sub bass range?  I use a high end receiver for my DAC in this system with a normal power cable as well.  Would I get better performance increase from upgrading sub cables or my DAC(receiver w pre outs) power cable?

Any specific suggestions for sub power cables, or DAC power cables that are inexpensive (sub 200 or even $100)

Thanks for your time!

Used to be the power cables don't do much camp, then I tried a few power cables. 

On my HT setup, I noticed that after installing PC's to my SUB's and amp, that the power draw on my power conditioner went up, quite a bit. At idle everything is drawing more power. When things start to hit, my current draw jumps up way faster and higher.  Sound wise, it's cleaner, but didn't really notice much more, maybe better dynamics.

The sub on my 2ch, took measurements before and after. Test tone, measure, change cable measure again. Got almost 2db higher on the test tone after a cable swap. Bass felt deeper, fuller. After a couple days, I turned down the gain on the sub.

My 2ch sub is a Martin Logan sub array, it had a ok 14g cord. Swapped it with a 10g. 

Weirdly, when I swapped PC's with my streamer, didn't really notice anything. Same for changing power supplies on my TT, no real difference.
