Anyone using a 27ix/270 with a Purcell?

I am currently using a Purcell to upsample the output of a Wadia 270 that is clocklinked to a 27ix. This works fine at 88k, but when usampled to 96k, I hear intermittent static pops that are similar to what I would expect "dirty" vinyl to sound like.

Has anyone else experienced this?
Any ideas for solving this issue?
