Newbie want to improve what I have


I am brand new here already purchased my first system. Probably made some mistakes. So I bought an NAD M33, Focal Sopra No 1 speakers, Tellurium Black II cables with an Isotek EVO3 Polaris. I am enjoying the system but realize I've probably made some mistakes. So as a humble novice I'd love some advice where to start to improve my system. I thought perhaps starting with the cables. Looking too warm this up.

You could have done a lot worse. Hard to make suggestions but tell us about your room and speaker placement. 

Nothing wrong with your choices! I presume the M33 is a streamer/DAC/amp? Then you are limited to the streaming services' music offerings. You don't know what mastering variation was used. Some are better than others. That is why I prefer to own physical copies, LP's and CD's, so I can choose the best versions.
