The DAC 9 is almost 10 years old and DACs have improved a lot since then. I also don't think DAC/linestage matching is particularly difficult, so my approach is/was to get the best DAC I felt would be the best fit for me in its own right, within my budget.
I have a Mola Mola Tambaqui feeding into an ARC Ref 10 linestage. It's a pretty fantastic combination.
