The sound systems

The previous threads on this topic are already a bit older and did not give me the answers I had hoped for. I would be interested in how big the difference between 8/10, 12/12 and Dynaudio really is. I also read something about a DSP 12/12. What’s different and why isn’t there any more? Did one of you have the 8/10 and have changed to Dynaudio? Mine had “only” the 8/10 and I was still thrilled – I found the sound more than good, nothing was rumbling or rambling, only the rear view mirror trembles at higher volume. Despite the lack of subwoofer the bass was very good and above all not exaggerated! Thanks for your help. LG Robin
