Have had mine just over a month. They sound great and are opening up. I would estimate I have about 100 hours on them. I kept my old system for comparison and enjoyment in a smaller listening room., Hegel H160 mated with Joseph Audio RMXL 25's Mark 2. a very good sounding system with a wide and deep soundstage.
The Sopra's are already deeper and wider with my Hegel H300, its like seeing Pro Ball when are used to Triple A, more of everything on all levels, the sound is so thick, a detailed wall of sound that keeps expanding with volume! When I turn it up, you are enveloped in the sounds, yet still sounds great at a low volume. So pleased with the speakers. Look forward to more hours and the speakers opening up further.
Fun times to be getting new gear.
