Heed amp experience with Tannoy speakers

I'm asking AoS members if they can share any experience they have with Hungarian made HEED amplifiers, which work with capacitor coupling and not DC one.

Their website describes:
Like the belt of a great turntable or the output transformer of a valve amplifier, the output capacitor makes for a great decoupling between the amp and the speaker. But the main advantage is the fact that a capacitor is an energy storage device. By design, this capacitor connects directly onto the speaker, with no in-between elements. Power delivery becomes rapid and precise. To charge this power element, we use a push-pull complementary Darlington transistor drive stage.

Is there any sound benefit for such approach? I have Tannoy Turnberry SE loudspeakers in middle size room.
Thanks for input.
