< $3000 speaker recommendation for tube integrated amp?


I’ve thought many times to disassemble my system as I move into retirement. I really do enjoy it so I’ll keep it for the time being.
I keep wondering what $3000/pr speakers would bring to the table, if any improvement? What are some better speaker recommendations < $3000 to compliment my tube amp?

My System:
_Mystere IA11 (40 wpc EL34) tube integrated amp from PrimaLuna
_Thorens TD203 turntable w/ their uni-pivot tonearm/ Ortofon 2m Blue cartridge/ Schiit Mani phono preamp
_Yamaha BDP/ Schiit Modi3 DAC
_DIY Seas Froy3 speaker kit from Madisound in 2003

Musical tastes vary from classical to classic rock, blues, jazz, and world.

Thank you,
Mike

Ref 3a and Tektons seems like good options too. 
GSM, a call to Zu Audio is a good suggestion.
Tektons are unusual looking speakers w their tweeter array. A little unconventional for me. Zu is a good looking speaker.
a discounted pair of Spendor A4 floorstanders will do the job nicely.  Spendors are the perfect blend of a fast, highly responsive speaker that doesn't come with any of the compromises associated with a high sensitivity speaker.  
great bookshelf speakers - Fritz Carbon IV Mk II for around $2,500 new. Had them for little under year - loved them ! Upgraded to Fritz Carrera 7 BE
One of the best speakers for tubes or a set amp is REF 3A MM DECAPO..the anniversity edition will produce imaging n soundstage to amaze u
