Help with a hum or buzz thru my speakers read ...


Help...
I have a pair of Aragon Palladiums and they are hooked to
Mirage OM 9 speakers with wireworld silver eclipse II cables..The amps have Transparent power cables on them and
the pre/processor is a B&K ref 20.. the amps are balanced inputs but the processor is rca.. I have purchased Transparent RCA to XLR ultra interconnects.. I have significant noise thru the speakers when there is no source playing.. but when I turn the power off to the preamp, there is no noise thru the speakers... also when the preamp is on and I disconnect the RCA to XLR cables from the amp.. the noise goes away... Coult the cables be causing the problem.... I am also using a Monster hts 3500 and a ps audio hospital grade outlet... Any suggestions...
Thanks for the help

There are a bunch of variables that you must research and give an answer:
1. connect the same interconnects cables from amp directly to any source that you're using with no preamp.
2. connect any different interconnect cables from amp directly to any source.
3. make sure that cables hooked up strong and if not you should bend the inner clamps so they're stiff enough.
4. connect different cables from your preamp to the amplifier and if the problem percist with different cables, your preamp is loosing the ground isolation and needs a proper service by technician.
