I've owned some Adcom pieces, and one of their pre's from about 2007. I've read a lot of owner's comments on Adcom pre's as a result. Most pan the later Adcom stuff. I know that I had issues with mine.
These days I'm running a Schiit Saga and after comparing it to the Parasound Halo P5, sold the P5. It's simply an amazing component. The sound stage is holographic and live sounding, it's the best my system has sounded.
I've also experimented with other Schiit gear and have become very confident that they know very well what they are doing. I'd say the Freya would be a significant improvement over your old Adcom pre, no question.
