Howdy. I also have a 1200 & went through a couple different setups before settling on the Shelter 501 & Krell KPE reference pre. I had tried a Grado Reference & their PH1 but felt the sound was a bit constrained. I had also tried a Black Cube & replaced it also. I find the Shelter along with the Krell pre gave me the widest sound spectrum and best bass response. Yes is was spendy, but worked out well for me.
