PSVANE ACME 300B TUBES
I recently received Psvane's newest 300B tube, the 300B Acme.
I let the tubes warm up in my amplifier for about an hour before playing some music - and the tubes will not be "broken in" for another 100 hours or so. Still, here are some initial impressions as compared to my Gold Lion 300B tubes (very good tubes for the price, but not trying to be the best of the best).
1. The air between instruments increased significantly
2. The image height increased by a couple of feet!
3. The amount of reverb heard in music and vocals increased greatly. Midrange is sweet, palpable and realistic.
4. The music had great dynamics that was missing previously. The snare has the right "bite" to it, the contrast between loud and soft increased dramatically,.
5. Sound stage imaging was more precise and had greater depth.
So far, I am very happy with the tubes!!
