Yes, Thanks Ernie...that is exactly what solved the issue...as indicated earlier I had all but given up, trying the Naim on the top, third and second shelf of my Atacama unit to no effect...but moving it just a few inches lower to the bottom shelf removed the "hum" completely.
I have since moved the amp away from the Atacama unit altogether, as far away from the turntable/arm/cartridge as possible....and now more than happy...A "working" Naim plus my new Spatia loudspeaker cable have made listening a joy again!......only problem is...I now have a gap in my Atacama that needs filling(for aesthetic purposes only of course).....

Interesting, and so much for the EMC Directive!

There are 10 kinds of people. Those who understand binary and those who don't.

Unfortunately the EMC Directive doesn't cover many HiFi products, in particular Turntables!

Just listen, if it sounds good to you, enjoy it.

Yes, that's true. Amp and preamp designers must meet EMC and ESD specifications, while turntable, cartridge and arm designers can do what they want. I think interconnects might be exempt too. Makes my job really easy (not).

That none should be able to buy or sell without a smartphone and the knowledge in how to use apps

The joys of so-so shielding by some other manufacturers. That said a large mains transformer or motor coil can be problematic. My P3-24's motor induced hum on the excellent Music Maker III cartridge, the latter was not to blame. I ended up fitting a grounding wire on the Premotec motor casing. |
