and the web sites for the power cords you so loudly proclaim are wonderful have no spec's when it comes to RFI attenuation.

Follow Ups:
for the effectiveness of their shielded power cords either. I use 83803 in one of my cables and 19364 in two others. Go figure.
If you want a working RFI filter you use.............
are you ready for this???????????????/
are you sitting down????????????????/
Here we go.................
YOU USE AN LC FILTER!!!!!!!!!!!!!!!!!!
Just like the stuff that Corcom etc puts in can, or a Tripplite Isobar.
Wire is not a filter, now go back and review AC electronics 101 and get reaquainted with reality.
d.b.
Don't you worship at the alter of Belden like SM?
Volex # 17660; Braid and foil shield for generally under $15.00.
And now for the next question; since you're so adept at putting up links maybe yopu would like to try and explain to me and the rest of us just exactly what the link you posted is saying, because from my experience with you on this is that you really don't understand what is being said or not said as the case may be.
One final note: The shielding is only as good as the ground the shield is connected to.
LMAO as usual;

The Volex is a good, but not great answer for low current devices. I would most certainly not use a wimpy 18 gauge cord with my 10 amp tube monoblocks. I believe it grounds the braid at both ends which may not be desirable in all cases.How do shields work? Shields are conductive layer(s) that trap stray signal (RF) with lowered transfer impedance. Some are aluminum. Better ones are copper. (I doubt that the budget Volex uses copper braiding.) Yes Dan, they selectively filter HF. With AC wires, the braided shield becomes the bouncer to drain the undesirables to ground. I chose to connect the braid of my 83803 flavor only at the plug end away from the component.
So, how is the collaboration with SM going on your next exciting alcoholics piece?
"The Volex is a good, but not great answer for low current devices."
What do you base this assumption on?"(I doubt that the budget Volex uses copper braiding.)"
I think you are wrong here: the foil is aluminum, and the braid is copper."Yes Dan, they selectively filter HF. With AC wires, the braided shield becomes the bouncer to drain the undesirables to ground. I chose to connect the braid of my 83803 flavor only at the plug end away from the component."
Ever look at the frequency response of this and compare them to an LC filter such as Corcom etc. and Tripplite?
Is that cable 30 to 40 db down at 1 Mhz?
"I chose to connect the braid of my 83803 flavor only at the plug end away from the component."
Why, whats wrong with a low impedance return from the chassis to earth?
I don't think you've done your homework here. You appear to be just doing the usual high end marketing dance.
Tell us; how much do you get paid to put up these silly posts? Do you get discounts on new equipment as a reward?LMAO as usual;
d.b.
The bitterness of your folded tent has become you. Speaking of which, how's that campaign to "marginalize the high end" going? Contacted S.P.E.C.T.R.E? You're sounding like this guy:
What do you base this assumption on?
If you want to use 18 gauge for regular 10 amp duty, have at it.
Ever look at the frequency response of this and compare them to an LC filter such as Corcom etc. and Tripplite?
A. I prefer using a combination of active and passive (shielding) strategies where useful. Each has its own role.
B. I will be happy to view that information. Since Belden (nor subsidiary Volex) provides such, then by all means present your evidence.
Only speculations. You do make it so easy for me, it's really laughable.
LMAO as usual;
d.b.
I have far more important things to do than to respond to your childish interrogations. It is they I find tiresome. On the other hand, I have humored them from time to time. You just don't like my responses!And of course, the current one concerning how shielding works.
nt
there ought to be a merit badge for you.So, how's your article on NFB for alcoholics going with SM?
So, if you believe that RFI is important, the design of the antenna from the isobar to the power supply is important.Given that, a simple shielded volex power cord seems to do the job just fine.
Will the shielded cable help then?Try this link: http://www.audioholics.com/techtips/audioprinciples/interconnects/bulletproofingsysteminterf.php
Go back and read it again. Maybe look for the word ISOBAR.
My apologies.
