I own a pair of Zu Omen def with a Line Magnetic 219ia. This is an expensive amplifier, but even the cheaper ones (518 and 508) are excellent.
Another good option is a relatively new amplifier from Hong Kong - KingKo Audio. The designer is a friend of mine (he was previously selling Rogue Audio, Line Magnetic and Zu, so he decided to create his product based on his own ideas and also the best from each brand he was selling).
His amplifier is small and perfect for high efficiency speakers. Top quality parts, extra care with the transformer and even a very high quality headphones tap. Also very affordable valves and gorgeous meters.
Can work as integrated or power amp.
The sales are exceeding his previous expectations and there is a very good review on the audio website DAGOGO.

Note: although friend of the owner of this brand, I have no interest or profits from his sales. I'm just giving a very personal and honest suggestion.
