Help choosing floor-standing speakers.


Hi, I'm currently looking for a pair of floor-standing speakers, I'm upgrading from a Triangle Titus 202. My budget is around 400€ - 700€, would like to buy used so I can get a better deal. I've looked around a bit and found these options:
JMlab Cobalt 815, Triangle Talya, Quad 22L, Infinity Reference 50, Davis acoustics Matisse, Triangle Scalene, Kef Reference Model One/Two, monitor audio rx6, B&W CDM-7NT
I listen mainly to classical music, soundtracks, jazz, and some 70s 80s rock. Thank you in advance.

C'mon guys, it's great that you are trying to help, but it was approaching a year for the first response to the thread. I may be wrong, but I'm thinking he has already bought speakers, and not even looking for answers at this time. Should he respond, guess I'll just start removing those feathers from the crow for my next meal.
