Absolutely take your time. Training your ears to hear the difference in speakers (and not the components) takes time. There are many different classes of speakers... like Sonus Faber like are natural and musical, B&W like big kick with a highlight on details, planar speakers are really fast with amazing mid range.
I would not expect to get it perfect the first time. But I would take a few trips. Go to places where you can listen to three or four different speakers with the same components powering them. Try and listen to the music and not the system. You may, like I did... purchase the pair that emotionally connects with you. For me... they all sounded pretty similar... and one pair brought tears to my eyes when they played one of my favorite songs. I could not tell you why (I could explain not 45 years later) But that was it... I emotionally connected with them and they were a great choice.
Probably at this stage do not put "get the best deal possible"... buy used to get something of higher value" unless you happened to hear something used that you connect with. Getting a speaker from the wrong family of sound, is not going to be as pleasing as getting a "cheaper one" with the sound you want. It's kind of like wine, choosing the right bottle may not be the most expensive.
If you want to start learning... get Robert Harley’s book The Complete Guide to High End Audio. Read while you are evaluating.
Get the right speakers and you will find yourself listening to music 90% of the time.
