Turntable Causes Speaker Cones To Excessively Move Rapidly

Wow! @audphile1 

I would never floor mount my tt behind a speaker.
 

@slaw I don’t have my table on the floor behind the speaker. It sits on solid steel amp stand between speaker and integrated. Concrete floor. Zero issues. I do plan to move it out of there eventually but I’m not in a hurry.
There would be more problems with a turntable on a top shelf of a flimsy stand in another end of the room than where it is now.

The Sabrinas are rear ported. They are placed about 4ft from the wall and there are bass traps behind the speakers. It’s all taken care of. 
 

To add…there’s no defined rule for a best place for a turntable. Wall mounting eradicates issues with suspended floors but the bass that travels along the room boundaries might still impact it. Heavy table on a rock solid stand is the key in addition to finding a good location.

My local friend just returned from having his Rega RP10 fitted with his supplied 

low hour Ortofon Cadenza Black lomc. 

Experiencing hum, right channel only. 

Thoughts?
 

@slaw Move all sources of EMI/RFI away from the phono cables and phono stage - transformers inside amps will impact it, power conditioners, wifi extenders, power cables. And plug the phono stage and the table into the same circuit with preamp or integrated to avoid ground loop. 

Thx for your replies @audphile1 😊

@slaw 

Glad audphile1 was able to offer his thoughts...hope that helped resolve the issue.  I haven't ever experienced hum from one channel.  All I would know to do is check all connections and replace cables where possible.

After some trial and error, found out his JC3+ has an issue. Thx for responding.
