Ferrite Cores for Power cords


I am new to DIY and just made two power cords based on the Oyaide Tunami cable and Furutech connectors I purchased from vhaudio. My understanding is that I can possibly enhance the performance of these power cords by fixing ferrite core cylinders/boxes onto these cords. I will highly appreciate your advice/comments on the following regarding ferrite cores :

- Where can I buy them and which are the good ones/brands ? Any online source for buying these will be great.
- Should I attach them to both ends of power cords or only one end is enough ?
- Is there anything else I should know when I use them to derive maximum performance from the power cords ?
- Is it normal to attach the ferrite cores on interconnects and speaker cables as well

Please share your experiences.

Thanks in advance.

Versalab "Red Rollers" are missed by Me, I got 6 in the '90's...lost one somehow. Adioquest made "Big Blockers", but not offered anymore.
Versalab also made "Split-rollers". I wanna find a couple, no inconvenience(struggle) to get past the bigger plug moldings on PCs.
In addition to my 5 Red Rollers, I am using the largest ones from Parts Express here and there. Under $4. bucks ea.
I consider them essential for Line Level connects.
Anyone got any Versalab "Split-Rollers" for sale?
