Ferite rings

Haven't tried them in a long, long time. Seems to me that they attenuated the highs to great ill effect. BUT, since you brought it up, I got curious and stuck some on the napsc. Let you know.

I have tried ferite rings just because I have some, not because I have some RF problems.
I believe that Naim electronics are somehow imune on that. I have put ferite on AC chords of CD5 and Nait2 and one on the interconnect.
The result was not good, I have heard some compression and lack of highs extension and all thin was been pretty much nervous (hard to describe). I have tried all combinations, but the main intruder was ferite on Naim interconnect. All others don't do any bad, but not even a good.
Ferits are finished on vcr, tv and pc. Better that than in the trash.

ferrite rings pretty much kill the music. Use only as a last resort. Unless of course you start with lifeless tuneless boring round-earth north american kit... in which case there's no danger!

I have tested these extensively......on signal or power cables they slug the sound..not recommended.
I use one on the earth wire from my prefix to the earth post on my 52..this cable should not carry any current, except(RFI) noise....it very effectively knocks out RFI without ruining the sound
