I just received my Cantata and spent several hours listening to it break in. I was using the Opus 21 prior. The BIG difference between the two while playing CD's is the fact that it actually sounds more analogue that the 21. Keep in mind it will take a bit to break in and should only get better. It accepts a CD easily and looks awesome. It is nice to be able to dim or mute the lights at night also. Awesome unit and it will probably cut down the amount bof time I spend listening to vinyl
