Martin Logan ESL 15A/13A Non OEM Speaker Power Cables

I added Pangea Audio AC 9SE MKII Signature Power Cable w/ Cardas Copper and it made a significant difference. I am very pleased with these - they are priced very reasonably!  https://www.audioadvisor.com/prodinfo.asp?number=PGAC9S2 Great speakers - which of these do you have?

Many thanks your reply, I’ll try them out and see, free returns so no issue there either.  I have the 13A’s which I really like, mainly a jazz listener with some chamber music.  Happy Thanksgiving!
