"Upgrading" my speakers

Hi Guys, this is my first time posting anything in here!

I recently became attracted to listening to vinyl records so i bought an old Technics SL-D2 and coupled it with my roommates WEGA JPS352 V150 amp. Up until now we used an old pair of JVC's (i don't even know what the model is of our speakers. The room is roughly 25 square meters and we sit at a distance of roughly 2.5 meters.

Now that you know about the setup here is my question: I am always checking all the used stuff apps and websites to check for speakers made around the 80s to early 90s since I liked the looks. We'd love to have something like a SABA Ultra HiFi Box but those as you all probably know, or I'm just looking at the wrong places, hard to come by... We looked up some other options but didn't find anything we liked the looks of.

We'd like to spend around 200-250 Euro on a fitting pair of speakers somewhere near us so in Austria and our neighboring countries.

Thanks in advance for the help, I am happy for every answer and tip regarding the speakers!
