New Schiit Freya or used Conrad Johnson PV-10AL/BL, or?


Looking to buy a line stage tube preamp with an $800 budget. Considering the options. I can use this preamp with either a Vincent SP-331 or McIntosh MC2200, whichever is a better match.

I also like George's analysis.  You may need to change the tubes on the Freya,  but I hear its quite nice.... as George mentioned about gain. On the Freya, be prepared that each stage,  Passive,  SS and Tubed will all have a different amount of gain. It can throw you off a bit.  Tim 
Thanks for everyone's input particularly George for taking the time for looking up the specs of my amps. The (unusually) high gain in most if not all of CJ preamps is a valid concern. The MC2200 does allow to toggle the input sensitivity between 0.75v and 2.5v which might work with the CJ pre but I'd rather keep my options more open. That Quicksilver pre also looks real good.
I have the Freya and it is very nice.I haven't heard the CJ but I did look at them when I was searching.The Freya also has 2 outputs which work well for me.One set goes to 2 Emotiva XPA100 Monoblocks and the other set goes to a Primaluna Prologue 5 .I rarely use the passive,it is either the Jfet or the Tube output.The Freya is made in America as well.Plus ,I kinda like their Schtiik and I can say I have some good Schiit man.
With the Freya you are getting a brand spanking new preamp Plus,the tubes are plentiful and mostly affordable.

You should also consider the Mapletree Line 2, you cannot do better at the $800 price point.  It can also be customized for inputs, outputs, gain, whatever you want. Hard to find used and they sell quick but new ones do look nicer.
