If you enjoy your instrument you will play more. If might just be a change not necessarily an upgrade. I will say that a ‘better’ instrument can be easier to play. As for the brilliant sound you are experiencing from the current strings. You could try different strings. Check out the chart at Shar Music which rates them Subtle to Direct and Warm to Brilliant. It also gives price ranges for the strings on the graphic.
Also Joy Lee did a nice video on upgrading strings. She has a YouTube channel.
Happy hunting.
