    I’m using these in a Primaluna Prologue preamp. I’ve been quite impressed with these tubes, good balance and a clean sound. They were kinda bright to start but opened up after about 10-15 hours. Excellent value for the money, Get em while you can. Very quiet and no microphony. Most test with close triode balance as well.

    Crisp, clear and linear, much like my Telefunken’s. Possibly a little bright but I’m using them with my Gold Lion KT77’s in a PrimaLuna Dialogue HP integrated. Probably a better match with my Tung-sol 7581A’s which tend not to have as much high frequency extention but are fantastic tubes with the PL.
