If you haven't considered room acoustics you should. This can have a very big improvement and the cost is excellent for the gains received. Also a Behringer DEQ 2496 can help alot. Otherwise I'd have to say speakers have a greater impact on the sound. At minimum read what others have said when it comes to room acoustics and learn what you can. This is VERY important if you want good sound. The average room has dips and peaks of plus or minus 15db! That is a huge non linearity in music reproduction.
You have a good amp and speakers. Being new you should listen to us old farts. If I had it to do over again I would have learned about room acoustics decades ago. Once you get that right then you'll be able to appreciate system improvements much more.
