Best Powercord - SIZE Matters along with price ???

All you cables guys out there!
Trying to upgrade my amplifiers main powercord, tube amp that does not have IEC.
I love the Audience Powercords but they are too thick for this application so I am looking for a powercord thats slim or small in diameter but sounds super relaxed and detailed.

The size of the Nordost Powercords are excellent, Vishnu, Brahma and some others, any feedback on this.
Even any powercords in bulk that you believe is great, do let me know.....

Thanks
