Mapleshade Double Helix

Par: Try and listen to the IC's on another system if you can (it may be a bad connection on one of the IC's and they are very fragile. The only hum that I have ever experienced in both channels that would not go away with cheater plugs was a bad power transformer.

Thanks for the response. Are you using tube or solid state equipment? I have spoke to Pierre at Mapleshade and he has been a great source of info however I still have the hum.I am using a Music Reference RM9 MK II and a ARC SP9 MKIII. The hum I am experiencing does not seem to be audible while listening. Still in the back of my mind is "how would it sound without the hum?" Again, thanks for the input.

Do you have the interconnects in close proximity to any ac cords, ac outlets or transformers?? They can be sensitive to all of the above. The instructions must be closely observed. Do agree with DeKay...I would call Pierre. He is a wonderful source of information. Good luck.

I am using the Double Helix digital cable with no difficulty. Try talking to Pierre at Mapleshade who is a wealth of information and good luck.
