I loved my H3... the Forte is just more of good thing. Just as the Cornwall is more of a good thing.... and on up the line.
Sometimes I will feel like an image is wrapping around from front to rear or sometimes things go well beyond the speaker.
They are great with tubes but also with good solid state electronics. I recently drove the Forte IV with my new Cyrus 40 watt integrated. It sounded awesome. I kept that amp in my main room for over two weeks. It has great detail and an excellent sense of pace and rhythm. It had no problem driving those speakers to generous levels. It didn't have quite the tone that I appreciate with a good tube amp but man it sounded good. Like Heresy, Forte really sing with a great amp.
I use mine mainly with a 7 watt 300b amp and they sound so good together.
