The Sonetto's are a great speaker. I had a McIntosh MC 302 driving them and they sounded very good.
I expect the Olympica IIIs to be good speakers but I'm not sure if there's going to be a significant improvement over the Sonettos.
The Sonettos were introduced after the Olympica's were replaced with the 'nova'. I would consider the Olympica Nova IIIs to be a significant upgrade.
Good luck in your pursuit of audio happiness!
