primaluna prologue premium int. amp + spendor sa1

Will this set-up work? Any recommendations?
You won't be able to really crank the volume as the spendors are rated at 85db, but since they are both known for being great in the mid range I think it could be quite nice. Let me know as I have the S8e's and was thinking of getting the Prologue One integrated as I like the el34's sound. Good Luck!
