AD1934 recommended Loop Filter component values


I'm using an AD1934 DAC for my product and the datasheet recommends some component values for the Loop Filter (see p.25, Loop Filter for LRCLK)

39nF cap,

2.2nF cap,

3.32k resistor.

I'd like to know if those values are critical or not, and if they aren't, what is the margin. They are a bit annoying as they are non-standard, and would add three lines to my BOM.
