Interesting, I also own m180s, and the kt 120 bested every kt88 I have tried, including the gold lions (which blew up on me by the way ) I am itching to try the kt150s.
Primaluna-TungSol KT120s in triode mode
Anyone have experience with this? I have a Dialogue 2 and enjoy triode mode and wondered how these would sound. I Have used kt88s, el34s (SED winged c) and gold lion KT-77s and am currently diggin' the KT-77s. Prefer open, airy, natural detail. All pre tubes in Dialogue are Mullard and GE NOS. Thank you for your time! Rest of system is: Scout 1.1 with Soundsmith Zephyr, Audio Electronics DJH phono preamp (nos tubes) and MartinLogan EM ESLs.
