Looking for suggestions vintage speakers under 600 eur for Sansui au 7700 amplifier

Hi all,

i have a good Sansui Au 7700 amplifier (i was told is a very good one from the time) that i use in my living room but my current speakers (Technics SB-CA01A) are average good, nothing fancy and i would like to replace them with something nicer and better.

I am looking for some suggestion on models to look at (I am based in Germany if helps). My budget is ma 500-600 eur for something vintage.

Few models that i very much like aesthetically: AKAI SW-117, JBL L56, Acoustic Research AR25, Yamaha NS 690, JBL L-15.

Music: I listen to everything although probably more bass-focused (house, hip hop, pop, electronic) and i usually listen through a bluetooth received plugged into the amplifier).

Happy to hear any suggestions/model names.

Thank you all in advance!
