I loved the sound of my modest system, until I upgraded my amp.
It seems you answered your own question - trust your ears and first impressions.
Take it from someone who has gone down the rabbit hole of trying to accommodate the one thing about my system that didn’t sound great to me. In my case it was a pair of large speakers that many said were great-sounding speakers. After about 3 years and too much money I finally replaced them - problem solved. In the end, the simple solution was best.
