XLR adaptor advice

I’m considering an offer on a set of Stealth Sakra interconnects at a very attractive price.  Unfortunately they are single ended and my preamp (D’Agostino Momentum) only accepts XLR.  I’m thinking about using Neutrik RCA to XLR adaptors for connection to the preamp.

i have a couple places I could put these cables in my system:

From a dCS DeBussy DAC to the preamp XLR in
From the preamp XLR out to a pair of Krell Evo 600 mono amps

Whichever position from above is left open would be filled by Stealth Indra V7, XLR.

Any advice/comment on using XLR/RCA adaptors? 
 I read most of the other threads already here on the subject and learned a great deal, but thought I’d narrow the question down to a specific cable/use...

thanks,

Mitch
