I called HFC this morning and managed to cancel the order before it was sent out. I'm now going with the Mundorf ZN's on the coupling stages as recommended - 0.1uF on stage 1 (12SN7 to 6V6) and 0.22uF on stage 2.
There's just more body and tone in the upper bass and midrange, with foil.
The last detailed comparison I did was Mundorf ZN vs. Audyn Copper/polyprop, and I slightly preferred the Mundorfs.
