Telefunken ECC82 12AU7 肋状板 ◇ 底部匹配对 - 柏林 '55 - 全新库存+

I replaced a pair of Genelex 12AU7 with a pair of Telefunken ECC82/12AU7 Berlin 1955 NOS+ for my Prima Luna EVO 300 preamp and completely altered the sonic and tonal characteristics of the sound stage. The later is now more opened, the low frequencies are tight and accurate, the mid-frequencies are breath-taking while the high-end is crisp and neutral. Both female and male vocals are front and center and present in my listening room. Chet Baker's flugelhorn is nuanced and smooth as well as Herbert Laws' flute. I have not heard Tony Bennett and Bill Evans' 1975 album sound so detailed until now. The holographic stage is starting to emerge after a short 10 hours of use. And the Telefunkens are very quiet. The investment was well-worth it. As a music major in college, I know what I like. Thank you SoundLumia for finding these rare vacuum tubes. P.A.H.
