“i put in this rca 7025, gave it a couple minutes to warm up, put in some brushfire fairytales and i was like, “damn.” i was pretty much floored at the improvement. ” Read
“Sweet, liquid, musical and responsive. Very dynamic and real sounding.”
This is a great overall tube with fantastic balance, and it definitely has no microphonics. I was hitting it with my finger quite hard with no audible effects, which is impressive. It offers a very smooth sound, and while it is not quite as smooth as the RCA 12AX7 Long Gray Plates, it is actually quite close. I have not tried the 7025 Long plates yet, but I would bet they sound similar to the 12AX7 long plates. Sound-wise, you get great bass, good but not overly sweet mids, and very good HF extension. There is no sharpness in the sound, which is a common issue with quite a few other gray plates. It provides a very transparent sound and a good soundstage. While this tube doesn’t really cross into “WOW” territory, it remains a great overall performer.
* Microphonics: Excellent, very sturdy and quiet
* Sound Signature: Smooth and transparent with great bass
* HF Extension: Very good, avoiding the typical gray plate sharpness
Final Verdict: While it may not be a showstopper, this is a solid, reliable performer that delivers a balanced and transparent listening experience.
