Ferrite Chokes on ALL pwer cables-bad?

MY IC's, with the exception of my Digital IC are all unshielded; Kimber KS1021 and Silver streak.

I removed all of the chokes and the sound improved a great deal, I'm not sure why I installed them in the first place.

Thank you to everyone :)

RPG -- In my previous comment I should have referred more broadly to the return conductor of unbalanced interconnects, not specifically to the shield. My comment and the contents of the paper I linked to apply to all unbalanced interconnects, regardless of whether the return conductor is a shield, a conductor in a twisted pair or braided configuration, or any other configuration.

The quantitative parameters that are involved, though, and therefore the degree of noise coupling that will occur, will of course vary depending on the specific cable design.

Just found this discussion while searching out a problem I'm having with some old MIT Z-Cord IIs...with two very different pieces of gear!

With both a PreSonus 16.4.2 digital mixer and an Onkyo Integra Research RDC-7 surround preamp, simply using the MIT power cord introduces a distinct digital glare to the high frequencies.

Anyone else notice a glare from ferrite-choked AC cords?!

I can make the noise come back simply swapping out the PS Audio power cords for these older MIT ones...

Great way to kill dynamics and stage.
