This tube has been specifically designed for Audio applications and has very low noise and microphonics.

“Sweet, liquid, musical and responsive. Very dynamic and real sounding.”
Great overall tube with fantastic balance – and definitely no microphincs. I was hitting it with finger quite hard with no audible effects 🙂 Very smooth sound, not as smooth as RCA 12ax7 Long Gray Plates, but quite close. I have not tried 7025 Long plates, which I bet would sound same as 12ax7 long plates. Sound wise, great bass, good, but not overly sweet mids, very good HF extension. No sharpness in should as with quite a few other gray plates. Very transparent sound and good soundstage. Now, this tube doesn’t really cross into WOW territory, but great overall performer.
