The Freya+ really is a remarkable preamp not just of the sound quality but for the features. Lots of inputs and outputs both balanced and single ended. The remote is quite nice. It's nice to have a remote controlled stepped attenuator despite the clacking involved with it. It has "passive", buffered, and active modes of operation. I'm pretty sure the active tube section is the Aikido circuit designed by John Broskie of TubeCad Journal fame.
I put the passive mode in quotes because it does actually go through some minimal active circuitry so that single ended inputs can be converted to balanced. It's a clever design. So while it still is a passive stage in that there is no buffering, the fact that no signal goes through it when the power is off means that there is some active circuitry.
All that said, I'm selling mine. My Supratek Cabernet gives me more of what I'm looking for in a preamp. I'm very happy with it. At 4 times the price I try not to think about the ugly reality of diminishing returns but I am happy with it.
