I did used Epos ES11 few months in many years ago.
My experience is; this speaker is not easy to drive it well, you need a quite good amplifier, especially class A amp like Musical Fidelity. The original speaker stand is very importance.
But if every thing get it ready, it sound great, clear, good tension of bass, good vocal too. But just not smooth enough in high frequency sound.
I don't know how's new model, could be difference, because the exiting company almost changed every thing.
