I’m currently breaking in a phono preamp and a new turntable. I’m 12- 15 albums in, I hear a difference already, break-in is real. My system is mostly Tube Based, so the tubes are progressively improving as they probably have only about 200 or so hours on them, depending on the component. My Aero DAC probably only has about 50 hours on it as I just put it in around November. (big difference from the native BlueSound DAC.)
Listen and enjoy, like watching your kids grow up, each step should be enjoyed, don’t get caught up in always wanting to be further along in the process than you are.
