“This is the 2nd pair of these tubes that I've placed in my Primaluna Evo 400 amp. Everyone's system is different, but for mine these provide an excellent balance of detail and sense of space while remaining very musical. In my setup they are performing better than much more expensive NOS tubes that I tried, because those were too detailed and made a lot of material sound excessively bright. Not the Radiotechnique tubes. As usual, shipping was very prompt and things arrived well packaged and in perfect condition.”

“Paired with 3 tonearms/cartridges, amp-premaluna prologue classic into martin logan esl speakers. Not sure what time will do but instantly pretty blown away by the difference these made”

“I purchased 10 Radiotechnique 12AU7s for my PL EVO 100 Tube DAC, PL EVO 300 Integrated Amplifier, and my beloved highly modified LAMM preamplifier. All my testing was done using different sets of cans ( DT 1990 Pro cans, HD 820 Closed-back cans ), and here are my results all in one sentence. There is an extreme level of clarity throughout the whole spectrum, the bass is well-defined, precise, and punchy, while the clarity of the mids is more refined, and still embraces the lush sounds of old-school tube amps, the highs are like a 24-bit on steroids, in essence, there is so much more detail and so profound. Note: All the 12AU7 tubes in each piece of audio gear have been replaced with Radiotechnique 12AU7 tubes and all three pieces of audio gear complement each other which creates a true balanced audio system. Good Day!”
