Q: iMac connected to external hifi/stereo system

I can successfully connect my Late 2014 5K iMac to my Parasound P3/A23 pre-amp using a mini-jack from the Headphone output to RCAs.

 

But there is a noticeable audio hum - particularly at higher volumes.

 

Anyone any ideas how to suppress that, please?

 

Thanks so much in advance :-)

iMac with Retina 5K display, OS X El Capitan (10.11.5), Clean machine... no haxies; no Microsoft etc
