will grado hum?


in the past I have had problems with grados and "s" shaped arms such as MMT. has anyone used grados ( $500. and up ) with the ALPHASON HS 100? other equipment includes UNISON 845 SE, JOULE 100 pre amp, and OPS phono stage, SOTA STAR SAPHIRE w/ hold down and VR4s
thanks

I'm using my Grado Ref. 1.2K price range with my older VPI deck,and a Morch UP-4 Arm and have no problems,But you must shield with a high quality phono cable to minimize any of this.
I have used unshilded cables here and things don't work,But I had to try out several from USEDCABLES lending library to get the right match.
No problem with Grado Blue and S-shaped Vintage Rega Arm.
I say no problem because in order for me to hear Grado hum I have to turn Volume to 3 o'clock, which I would never do while listening.
