Mr_bill...yes, all 4. I even have a few extras and they last a very long time at least relative to power tubes. 6SN7GTB. Stereophile rated the Freya + "Class A" even though it has lots of features...
Schiit Freya + Class A in Stereophile
I know there are a lot of audiophiles who don't think sterophile knows what they are talking about but I think its' pretty impressive that a 1000 preamp is put in the same category as 50K and up. I can't really believe that the Freya + is that good. I have one and do think it's pretty amazing for all that you get and you can really make it even better with some better tubes. I am constantly blown away at the sound of the Freya + into the Decware Zen triode amp. 2K for the combo and just about the best sound I have ever had in my home. Great news for less well heeled audiophiles.
