I have a schiit freya and tung-sol tubes are the best ones that I have used so far. The preamp came with JJ electronic tubes which were mediocre. Then I bought PSVANE 6SN7 Vacuum Tube UK tubes and they are good sounding with a decent price. Then I bought PSVANE Tube Cossor globe tubes and they were a little better with a steeper price but wasn't really happy with the clarity of them. Then I tried PSVANE CV181-SE Vacuum Tube Carbon Crystal Globe Tubes and they were pretty good but expensive. Then I bought the Tung-sols which sounded as good as the cv181-se tubes right out of the box. And as I write this I have about 80 hours of burn in time they are the best ones so far without question and the price for them is relatively cheap. I am very happy with them and will probrably end my tube rolling and stick with these. Highly recomend the Tung-Sols. Update 1/3/24 : I have bought some different nos tube, GE, Ratheon, and best of all sylvania jan 231vt which are the best I have tried so far. The money I've spent on tube rolling is rediculous. Old american military grade are the best
