Unless there is something wrong. A BIG upgrade. I've had both, stock it will better the Freya, if it has any upgrades it just gets better. 6922s (If I remember) I used Telefunken and Blackburns. I'm not a Line Stage guy. But BAT, VTL, AR are serious gear at 30 years old, WAY beyond the little Freya brand new out of the box.
Something else I didn't like about the Freya for a preamp it runs HOT. The sound is pretty neutral. It worked a lot better with a contour (passive GEQ). I liked the weight and the cool little remote too. Sure had great customer service.. The Freya..
