Hum after replacing tonearm cable

After replacing my entry-level tonearm cable with the high-end one there is now a very audible hum once the turntable is on and its motor is spinning. Moving the turntable around, away or closer to the phono stage or rotating it 180 degrees or upside down did not make any difference on hum. It is consistant regardless where the turntable is or how far or close it is to preamp or amp. The hum is equally loud in both left and right channels. Is there anything that could be checked or done to fight the hum other than switching back to my entry level tonearm cable?

what do you mean by high-end cable?

I suspect it is not 100% compatible or the new cable you bought has a design defect. If possible, switch back to the original cable and test it. Then power down (for about 5 minutes) and test the new cable. This is so you can figure out if there is intermittent failure or consistent failure in the new cable.

At any rate, you could always flag to the manufacturer and get your money back.
