I have use the Avanti III's for a number of years. They are great speakers. But there are ways to make them even better.
Adding an AudioPhysic subwoofer like the Minos changes the presentation considerably, not just in lower octave extension, but in spaciousness and ambience retrieval generally.
I also use a Townshend super tweeter, which has the effect of creating a more realistic soundstage and improving palpability, especially to voices.
Finally, each of the speaker footings has a Finite Elemente Cerabase screwed into it, which cleans up effects of cabinet and air borne vibration and leaves a very, very clean window on the musical performance.
