DV Tubes Which ones to get

So a friend and myself are splitting the cost of a matched pair of Telefunken 6080’s for our Dark Voices what do people suggest as a Pre tube I have DT990,DT880( both 600ohm) and Dekoni Blue Fostex ??

If you are coming from stock and don’t want to spend a ton of money buy a new production Tung-Sol 6SN7GTB. NOS tubes, well… It’s subjective really. Try and find 6sn7 rolling thread on head fi. You can find small reviews/notes on the first post for most 6SN7 variants from RCA, Raytheon, Ken-Rad, Sylvania, Tung-Sol etc GT’s WGT’s WGTA’s GTB’s, VT’s, CV’s and so on. Have fun down the rabbit hole. I’ll be waiting at the bottom lmao
