I currently have the Freya, Mimby and Eitr. I have been very happy. i preferred the Mimby/Eitr over the Wadia 121 that I had before. The Wadia is also a pre and a HP amp so not apples to apples, but there is a wide margin in cost ($400 vs $1200). I have been happy with the Freya. I needed more gain than the Saga would provide. Upgraded 2 of the tubes for a decent upgrade. Not sure of other balanced, tube, remote-controlled preamps for this price point. FWIW, I'm using with a DIY Pass F6. I am a happy customer and would consider more. i suspect the Vidar is nice for the price. Some reviews have liked the Saga more than the Freya. Do you need the extra gain or balanced config? Not sure about the Eitr. i probably need to take it out and listen a bit. I am using a win 10 PC USB out so I suspect it helps.
