I dont know about the Graham 1.5 but I do have the graham Phantom, I used the Benz Micro Ruby 3 with it, but have switched to the Lyra Helikon mono and Lyra Skala Stereo.
I am impressed with the difference, I have had these carts for about 2 months now and am not planning to move to any other.
I have heard the Ortofon Kontrapunkt B but on the Rega. So I cannot comment on the differences with the Graham. I have moved form the SME V to the Graham Phantom, this move was primatily due to the MONO and STEREO carts that I use, after changing the carts have to do adjust the cart all the time no fun but with the Graham do it once and change the wands. Love that Feature and now my music is much better as well.
