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.

wilfredt, after reading this last night I played around with some of the ferrites I own. I tried 3 in the basement on my 20 amp circuit that powers my system. This was a nice improvement. More natural and smoother.

I also tried 3 on my virtual dynamics cable for cdp. One clamped on all 3 cables of the virtual power cord. This was another nice improvement. same as noted above.

I actually orded 60 of these on ebay and they seem to have the nicest prices. I bought some larger 11mm openings and larger ferrite to get more of the larger cables.

nice and worth the little expense considering how much these places sell their tweaks for.

Willfredt,

I bought mine from Rogerdeane on ebay. I bought a ton. Actually all he had, but I am sure he will put more up. He was great...bought wednesday and recieved friday.

I have 60 of these things and will put them on everything in my house thats plugged in including every circuit that leads into my breaker box. Putting then on my systems 20 amp circuit proved to lower the noise.

the ones I bought have a nice 11 mm opening.
