noise from cd player connected to another amp, why?

[Mantra]

Hi

I have in a row , a cambrige , rotel , marantz and denon
a marantz cd signature is connected to my marantz amp , with good cable

but my marantz amp is off and my marantz cd player is playing a cd , i can hear some noise/music on my denon and other amps (when they are on)
as soon i stop my marantz siganture cd player , this noise/music ,is noise mixed with music disapeard

it' s very strange , should i buy double shielding like KabelDirekt , europe amazon

have you notice some issues?

thanks

Can you clarify what I’ve highlighted in bold? What are these devices and how are they connected to each other?

If your Marantz CD player is connected to your Marantz amp, why are you playing music with the amp turned off? Some context is needed.

Deutsch? Wie sind die Geräte untereinander verbunden?
Genauer: Sind die Verstärker miteinander verbunden?

Having the components on top of each other may be a large part of the problem.

hi
are you sure?
have you your components on different places?
thanks

1 <IMG> is worth a thousand words.

My hunch says it's some sort of ground loop, but without knowing what the devices are and how exactly they're connected it's near impossible to pinpoint the problem.

Sounds like crosstalk but between different amps?

Again we still need some context.

What are the components? Listing brand names doesn’t tell us what anythung is. Are they amps, CD players, DACs? What is connected to what? How they are stacked shouldn’t be relevant other than for ventilation depending what these components are.

You need to provide info on how you have these units connected and what they actually are.

Components power transformers can create fields that can be picked up by other components sensitive inputs or by poorly shielded interconnect cables.

Hi
I have avoided many time shield cables ,and i have often bought 99% copper without shield just because several friends told me they do sound better

do you think many shield cables on amzon are pretty great?
thanks
sorry for my poor english

Take some pictures of the connected components (rear panels/wiring). Make it clear what is connected to what and what specifically the issue is.

Also, why not use your own words and let https://translate.google.com do the hard lifting?

Always use shielded cables for interconnects.

Many coax cables on Amazon don't have great shields.
Look for cables with a heavy braided shield.
