Hi,
I see that combak harmonix and a few others make zobel filter logged in an interconnect to put at the input of the preamplifier or integrated amplifier.
I'd like to try it, but I'd like to avoid an impedance mismatch? At your sense what kind of values could I try? I heard such zobel where done to filter HF and that some of these filters where done to filter 20ghz.
Thanks a lot: David

What are you talking about?
What is 20ghz?
Zobels, when used, are usually located at the output, or exceptionally for a speaker, at the input.

A Zobel network is used to maintain stability by ensuring that a misterminated cable does not impose too high a capacitive load on a buffer-type circuit. Unlikely to be needed for your application, unless part of your equipment is unusually poorly designed..

The dnm way: DNM Products - ZRTN and High Frequency Termination Networks
comback harmonix: ENACOM AUDIO NOISE ELIMINATORS
In these 3 products the main idea seems to remove HF from the signal and I think they use zobel with a tiny cap (maybe 0.01uf) but I've no idea of the resistor value. The main problem is to not cause problem for impedance matchning between cd player (mine is 600 ohms output) and the srpp of my integrated amplifier.
An idea of the resistor value?

I quickly scanned through your links.
I did not see "Zobel" mentioned.
I did see RF and interference mentioned.
I think these are simply RF filters to help attenuate all the mobile phone and other wireless domestic rubbish you are adding to your audio circuits.

A 10 cent cap (small ceramic disc) and possibly a 5 cent ferrite bead or a small inductor. This is only needed if you're actually experiencing RF interference (e.g., hearing cell phone or radio signals through your stereo).
Reading 6 Moons and ad copy from cable companies is guaranteed to lower your IQ.
Sigh! If only I wasn't so honest and so well educated I could make a fortune by taking money off ignorant and gullible audio fans. First I would need to spend some money on a good creative writing course, but you always have to speculate in order to accumulate. Even if my products didn't sell I could always make a few bob by writing fiction for an audio magazine.
