It is dependent on your preference, and if you want to try a DAC maybe ask iFi as to what is a good match, they have a lot of dacs and probably have a sense for what matches your setup.
Denafrips Iris vs ifi spdif ipurifier 2
I have a Bluesound Node N130 > coax out> ifi spdif ipurifier 2 > Peachtree GaN 1
Would Node > usb out > Denifrips Iris > Peachtree GaN 1 be an improvement?
Would using both of them in my path be beneficial? Is there a benefit of reclocking at 10Mhz vs 45.1548/49.152Mhz
