Also if you have your phono stage plugged into another circuit from where your preamp or integrated amp draws power, it may cause hum due to ground loop.
Hum with TAK CU phono cable
Bought used TAK CU kimber rca to rca phono cable with its dedicated ground . When I inserted on my Ned Clayton step up transformer output to parasound jc3 plus it started humming, my turntable is a rega planar 2 with fixed rca cables and my understanding Rega grounds its tables through the left channel. Kimber specifies that this cable is shielded, I have not connected its dedicated ground cables as I don’t want to cause other ground loops .Does anyone have experience with this Kimber TAK CU cable , I love the sound I am getting from this cable but not the hum , don’t mind putting my Mogami 2549 cable back in as it has a good sound as well . Any info would be appreciated

@chrisocr have you tried what I suggested above? To have the phono stage run out of the same outlet/circuit as your preamp or integrated? That’s should clear out the hum. |
Yes I have , I apologize for late response and makes total sense, my turntable was connected to a separate source , so i joined the TT , phono preamp , preamp together with my power amp circuit. Did help , still slight hum and I think that’s the best it will be for now , I can live with it as I truly enjoy this cable compared to my Mogami . I believe since I am using a step transformer the 20:1 gain I am using with my denon 103r make the hum more audible at higher volume but in reality it’s way over my normal listening volume , at my normal listening volume which is plenty , the hum is hardly there. Kimber although says this cable has shielding, it seems it has less than average and it relies heavy on their special braiding technique to reject RF noise . But all in all I’m happy , thank you , I am new to these forums and very impressed with the support from the Audiophile community, applause 👏 from my end to you . |
@chrisocr glad it helped! Don’t forget the step up transformer should be in the same circuit with phono stage and preamp. |
A transformer is passive and doesn’t need AC so it isn’t clear what you’re trying to say here. Obviously the transformer can’t work if it isn’t in the phono circuit.
I think that depends a lot on the specific turntable and pickup arm. |
