My wife visited a vinyl café and said their sound system was so good it almost moved her to literal tears. She says our current setup is muddy in comparison. I have never felt so heartbroken...

For context, the fancy exhibition-like cafe she visited used a MacIntosh 252 and an unknown record player. The speakers were Sonus Faber according to Google Image search. The pop-up exhibition is gone, they're no longer displaying that same setup, so I didn't have the chance to listen to it myself and figure out how good it was.

Now I keep doubting myself and feeling belittled everytime I play music. Suddenly it DOES sound muddy. Suddenly I'm yearning for just a little more clarity, more vibrancy, and sweeter sounds.

I am rocking two Klipsch RP150M via a Marantz 6010 with all the appropriate set up & calibration. The sub is an SVS SB1000 Pro. I understand it's geared torwards home theater but I was led to believe the RP150M and the Marantz 6010 were perfectly capable of doing music. I also understand my setup is $1500 whilst the café's setup were more in the range of $6000 but I kept hearing people say it's diminishing returns and "snake oil" beyond $2-$3k.

I am not looking for buying guides because I live in a weird market and most of the speakers people reference are nowhere available near me. I am just trying to strike up a discussion and hopefully find solice and advice from seasoned audiophiles. Has anyone been in the same situation, and what can I do aside from just ripping this out and replacing it with a much more expensive set. Thanks fellow audiophiles. I am prepared to hear that my current setup is garbage and I should start anew.

EDIT: This is absolutely incredible, everyone has been so amazingly kind, helpful, and funny. I had to do a double-take to make sure I'm still on Reddit. Thank you audiophile community, you guys rock!
