You definitely can use more power in your space at your listening distance. It's actually a good thing you didn't jump to an amp right away because you'll now have a basis for comparison when you upgrade and you will appreciate upgrading even more.

Imagine a newbie, who has never even listened to a system, because say she's a student who lived at the family home with a Sonos or Bose or headphones. The first system she buys is active LFRs. How would she know it's good? So it's better to start off with a hand-me-down system and work up to appreciate goodness.
