Thanks to everybody, my system is tweaked in many aspects and power cords are the next target. (This is the reason of my post.)I made an extensive listening session and I prefer using ferrite in my case. I used the standard power cables that come with my hifi components, since my shielded cables are not ready yet. I mainly listened to classical music to better discriminate (well, I could not resist to listen Bob Marley as well :-) Clearly, the following observations are subjective and apply to my system+ears:
1. Apparently, there is less SPL (so that's why people complains about dynamics) and you need to increase the volume level; but you gain precision in the sound scene, which becomes clearer and more detailed (for example, the different groups in the choir of Haendal's Messiah). Some loss of dynamics is not a problem in my case, since I have efficient horn speakers.
2. Highs are indeed rounded up, but this is good in my case. My speakers are very revealing and, removing the ferrite, the sound seems to be harsh. I'm currently keeping the ferrite on the temporary power cords.
3. If you decide to use ferrite, it's more effective to use it on all power cables and wires, otherwise you compromise the signal in the cables not using ferrite (see Al's post).
4. Using the ferrite on the earth ground alone, does not change the sound as much as using on all of the three wires.
Some may agree and some others may disagree with the above observations, since listening is based on a personal taste at the very end. I experienced that some tweaking is effective, but I'm surprised how ferrite rings on power cords can change the sound.
Cheers
