Hi Plakey,
The amp would definitely work with higher-impedance speakers, yet I would guess it would lose a bit of power in comparison to driving a 4- or 8-ohm speaker.
With the low-power amplifiers of Decware, I almost always like to use a high-output source, more than what the technical specs say. For instance, the SE84UFO asks for an input 2.0V for full output. I am currently running mine with a Copland DAC215 which is at the same time a tube preamp, and the combination of the two is great.
Similarly, I recently gifted my SE34I.2+ to my girlfriend. She has a Hegel HD2 DAC with only 1.0V (or 1.25V) of output which is far less than the required voltage to run SE34 at full volume (the new version needs 2.5V but the one I have might need less; definitely at least 2.0V though). Anyway, I coupled the SE34 with a tube buffer/preamp by iFi which has a 7.75V max output. The combination sounds great with a slam and control on bass.
So, if I were you, I would couple the SE84UFO with a nice preamp and would not worry about running it with your Zu Omen's. I am sure they will sound pretty good.
In the meantime, I would like to hear your thoughts about the Omen's as I am fancying ordering a pair of the Dirty Weekend version. Particularly, how is the bass response on those speakers? I am considering replacing my B&W DM630's (at 91dB efficiency) with them...
Best,
Alper
