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
