I have a Freya+ on order and just sold my original Freya today. A friend sent me some matched NOS Canadian GE 6SN7 tubes (two pairs of matched tubes, not a matched quad) and the difference was night and day over the stock pairs of Russian 6H8C Schiit provided. Tighter low-end, better detail resolution, more holography, more natural vocals, less fatiguing... everything was better, by leaps in some cases, stepwise in others.
One of these GE NOS tubes seems to be a little noisy though, like random bits of static that needs to be discharged periodically. Creeps up now and then, and then vanishes for a while. Be interesting to see if it's a permanent phenomenon, or if it's something the tube just has to work out for itself... or if it needs a firm tap to dislodge something that shouldn't be lodged. (hehe)
Anyway, I found a YouTube review ( https://www.youtube.com/watch?v=LwMXMtSprxI ) where the creator mentions using Canadian GE tubes. I found the video after I already had these tubes in-hand, but I agree wholeheartedly that they definitely take the (original) Freya to new heights.
