Tag Archives: 12AU7-T

from customer Steven P. by email:

“I recently purchased two pair of the Psavane tubes, 12AU7 and 12AT7. I am not the first to tell you that these tubes are excellent. Bass is tighter, there is more overall clarity, and soundstaging is more precise. I am now off the NOS trail….”

I am reclining in my listening room thoroughly enjoying The Rite of Spring due in no small measure to the Psvane 12AU7 Reference Vacuum tubes. I just recently purchased these new production tubes manufactured under tight tolerances in the Shuguang tube facility in China. The Psvanes replaced gold pin EH 12AU7s. The EHs were good sounding tubes in my heavily modified cj tube line stage. The Psvane’s bring a whole new “sophistication” to all aspects of sound. Most notable is a complete lack of “glassiness” in the upper midrange and treble, a smoothness to the musical texture without any loss in detail. The soundstage is open and natural. Bass is powerful and tight. These tubes are very quiet, a characteristic missing in my trials with NOS Mullards. Yes, they were warm and “musical” but the several pairs I used were always noisy…losing their vacuum?
