Holo Serene vs Denafrips Athena (anyone compared these preamps?)

I have a horribly moronic (potentially) question, but would I be able to use an XLR to RCA dongle for the inputs? Like The Athena looks amazing but I run all single ended.

Also, I'd like to hear more of your thoughts on the Serene @jnds 

@gochurchgo  Why, it supports single ended?

@smodtactical  it has a single set in and I’d need 2 sets (DAC and phono) but I guess I may get a balanced DAC in the future so it’s probably moot.

still curious about both of these preamps. What little I’ve read about each has been overwhelming positive.

Oh I see. Ya maybe grab a balanced dac if you are also running phono.

@gochurchgo so you were thinking about running a phono premp through the Athena? I was thinking of doing the same but have been told that because the Athena has unity gain... I'll be making my life more difficult that it has to be. I dont clearly understand unity gain.
