At least 1 1/2 years ago, maybe longer I purchased the Schiit SYS passive preamp to use as a back up in case my preamps ever were in need of repair, for $49 I figured I couldn't go wrong.
I purchased a class D amp that I wanted to try in my second system which has an integrated amp and no access to the preamp section.
Yesterday, in went the class D amp and the SYS passive preamp.
I was very pleasantly surprised by both the amp and the SYS.
Although I have not heard the Freya or the Saga, I'm in agreement with you, either one would be an asset to your system.
