What one change to your room, system, or setup made the biggest improvement?


Mine was acoustic treatment on the walls and ceiling.

Room treatment (DIY), placement of speakers. --- Pearlacoutics Sibelius speakers, getting REL T9 dialed in right. --- Zesto SUT w/ Rega Naia

After I bought my Harbeth speakers I made some diy bass traps and put them on the wall behind the speakers. Music just jumped out at you. That's the best description I can think of. I did a before and after with my son one day. He heard it too. It wasn't subtle.

Vibration control on the turntable - putting a Townshend platform on top of a wall shelf to hold the turntable.Double treatment yes, but more than worth it,

Probably was my speaker upgrade, but that was a few months ago. My most recent change: Transparent Speaker Cable Plus > Ultra was significant. Upgraded Moon amp and Ultra interconnect arrive on Monday. Looking forward to the change.
