Currently I am using the Phasemation T-1000 step up with my Koetsu Black Goldline (latest production )
The Phasemation Carts do have very similar coils in the 4 to 5ohm region, so the Phasemation step ups are a good match to Koetsu as well (to my ears) , I tried different step ups before, like Ikeda, Etsuro, Kondo, but they all are the best with their own cartridge designs.
