I noticed that your are still using the 32X D to A. I presume that you are driving it from the digital out of the SACD player. I am somewhat surprised.
Last year I went from the Krell Studio to the Marantz SA14 SACD player, and after breaking in and proper set-up, the internal dac surpased the use of the Krell. As much as I liked the Krell DAC, it is definitely older technology that is not up to the Marantz.
