Schiit Freya plus. Is this an upgrade?

i believe the Tung Sol is a reissued tube from Chinese origin... not that this makes it a bad tube, but not an original 6SN7 which is a beautiful thing ion the right circuit. I hope the current 6SN7 that Schitt sources is great as I will probably go the same route with the Freya +... by the way, I used some Tung Sol brown base EL34 tubes before and they are the stuff... mostly as they offer up a stout sound and last a long time...

from what I have read, all the new production tubes come from just two locations - one in China and one in Russia. Only the brand name changes....

thanks for those performance specs. i am looking hard at this Freya+ although a ChiFi model is alot easier on my finances right now...   

is the Freya+ a better unit than this lite audio ls60?
