I have two Aegir run in mono with Freya+ , Ares II connected to Klipsch Forte III speakers. I also have the Lokius which I will use as a switch for a Decware super Zen triode SE84UFO2 (on order) w/ a 2-Way Amp Amplifier Receiver to 1 One Pair of Speakers Selector Switch. So I can switch between the Mono Aegir and the Zen triode amp. The combo that I have sounds excellent, but I have nothing to compare it to that is why I bought the Zen triode.
