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.
