Speakers for Audio Analogue Primo

Any suggestions for bookshelf speakers under $2K to match with Audio Analogue primo amp? Mostly listening to vocals and jazz. Considering Spendors S3 (but heard that the amp may not be able to drive these well). Require warm sounding speaker that also gives more bass.
I have paired them with Vienna Acoustics Haydn Grand, and i'm more than pleased. VA is warm and unfatiguing with the very good bass for its size. i think you can't go wrong with this duo for jazz and vocals.
