TK16
Headphoneus Supremus
Those tubes I found quite harsh on Schiit amps, MJ2 and Lyr2 on my equipment, ears, and my preference mostly towards warm tubes. Opinions will vary in audio. I sold it here for what I paid for them.Well, I'm out as I am not patient and obviously do not know where to look. Or maybe I'm thinking of some other TFs.
