One Cord To Rule Them All

Does anybody have a preference of solid core wire over stranded?

Yes, for interconnects and speaker cables, but I believe solid core wire is not recommended for power cables due to the higher potential for breakage due to repeated bending.  There have been a couple of folks who have discussed that, in their opinion, Romex would actually sound pretty good as a power cord but is not recommended because of the safety issue.  I have never tried it.

Here is my thoughts. I went from a Shunyata Research Anaconda Alpha Cable to a Pangea AC-9 and then to a Pangea AC-9 SE Mk ll. The Pangea AC-9 SE Mk ll is a 7awg cable as appose to a 9awg. I found out from my system that these cables are better than the stock cables and of course adds a better look to your system. IMO don’t break the bank on power cables. The price difference between the 3 doesn’t outweigh the difference you will hear. Don’t be fooled. I feel the cable you already have, is plenty and will continue to do the job. This is just my opinion and my experience of owning these 3 different cables plus others not needed to be mentioned. I hope this helps. 

Yes, it helps. I don’t want to spend $300 just to feel better without it sounding better.

Exactly. That's why you find any UL-listed solid core power cords.
