Lumin U2mini or ?

I appreciate these are slightly different machines but I am considering adding the following to my PontusII and Willsenton R8 set up as an additional source to the NUC/Singxer su6 :

Lumin U2mini or Primare CD15 Prisma

i do have quite a few CD’s so the CD15 is attractive

i do use a Singxer SU6 already which would also work with the U2mini

would welcome any thoughts
