Don't use your interconnects as skipping ropes whilst playing Led
Zeppelin
I think that Jimmy applied the skipping rope technique while his one of
a kind (albeit sloppy) virtuosity in the studio allowed the magic of a
Page solo

As mentioned above, 50/60Hz hum is probably more to do with an earthing
(ohmic--current loop etc) problem. I rechecked my electrical theory on
Wikipedia. A short article covers it fairly well there:
http://en.wikipedia.org/wiki/Electromagnetic_interference
A relevant extract is as follows:
It's late here, but last time I did the equation, AC at 50, or even 60Hz
had a wavelength of several kilometers. ie you needed an ariel of that
kind of distance to pick up anything via electromagnetic coupling. I
have transformers, and a pile of power wires behind my system. I have
never heard
I can very easily pick up a 60 Hz hum in my subwoofer interconnect if it
should parallel a power line for more than a few inches.
In fact the hum is strong enough to keep the subwoofer amp on (it's an
auto-on, auto-off amp as sub amps usually are.)
Perhaps I'm using a poor interconnect, but
My sub interconnect is coiled around /piled on top of a 1500W
transformer (220/110V). The sub (Velodyne) can output a frequency note
from 20 to 160Hz which is picked up by a mike and displayed on the TV
through the AVR. This to allow the sub to be blended in with the
room/main speakers. There

Not really, because fixing it is so easy - I just futz around with the

A cheater plug may be a diagnostic tool, but shouldn't be left that way
as the ground pin is there for a reason. Things
Cheers to the forum!
This is a rich resource and I have benefited immensley from the
knowledgable and helpful members here.
With that in mind, here is my Q -
The rat's nest behind my audio stand.
Let's hear what you do about routing the assorted separates, wires,
cables, PS, etc. in order to
I find the only EMI that's truly audible is AC power with
interconnects.
Just keep them separated, and cross at right angles.

powerstrip and RG-60 coax ICs completely eliminated all hums and noises
for me. As far as clutter, I used those slit flexhose for bundling the
ICs together and keep them away from AC cords

Best practice is to have short wires so there is no rats nest.
Using a one meter cable when the gear is stacked on
powerstrip and RG-60 coax ICs completely eliminated all hums and noises
for me
Not sure what you mean by RG-60 coax ICs?

Coaxial cable usually used for cable TV. You can get special
connectors to turn this cable into interconnects. Much cheaper than
boutique cable.

(Can't remember if it's RG-6 or RG-60 that's used for cable TV or
satellite TV signals. Anyway, you get the idea.

Interesting...analog and digital IC?
Can easily do both. Take a look at the bandwidth...huge! Meant to
carry signals in the MHz or GHz range.
Does the foil shield in the coax effect noise rejection?
Yes, but this depends on the type of RG cable used. Some have a
w/ solid core center lead and web-wound shielding, can go great distance
w/o losses. It was my final answer 20 yrs ago after countless swapping
around to kill the last bit of airborne noises. They are too cheap and
plentiful for audiophile uses ;^)
