I have had some extended listening time at my friends shop (some weeks worth of listening). The Zeus is a powerful-sounding amp with good (though not great) delicacy in the highs. It has a slightly dry but none-the-less emotional midrange. The Rogues does female voice and jazz very well; it also can rock out! Very easy to listen to. Gobs of impact on the bass. Nice image. I spent many a pleasant day listening to music through that amp.
The ARC amps, IMO, seem to concentrate on the highs and low-level details to the detriment of the low mids (for some peoples taste). The Rogue seems to pay more attention to the mids and below, while still being quite competent on the highs.
The Zeus uses 6 output tubes per channel meaning that, at 225 watts, the tubes are being run on the hot side. I don't know how this effects tube longevity on this amp, but all else being equal, this usually leads to shorter tube life. Check with the factory.
