Graham Phantom or Morch DP6 ?

Does anyone have first hand experience with these two tonearms or know anyone who has heard them both ? For about the same price in the used market I can buy either a Graham B44 Phantom1 or a Morch DP6. Both are unipivots. I want to use it with my Verdier. I know that Graham tonearms come with a very easy setup procedures but I am more concerned with the sonics. The cartridge used will vary between a ZYX, 47 Labs or Grado. Will anyone be able to tell the difference between the sonic presentation of these two tonearms ?
