12AU7 Genalex or Psvane for Cayin Hybrid Integrated H80A

While I have limited experience in Tube rolling. I replaced Sovtek Tubes in one my Pre-Amps with Psvane 12AX7's & 12AU7's. Initially much more resolving but very bright. After 70 or so hours the brightness subsided. Very quiet, highly resolving Tubes, better dimensionality, soundstage, musicality etc. Very happy with the Psvane's so far. In no hurry to try others in the immediate future.

If you can get past the initial brightness of the Psvanes, then once they settle in IME the Psvanes are a real winner. After the 70 hours they have that "Goldilocks" "Just Right" signature sound to them, at least in my Set up. I feel they do favour resolution over warmth, so may not be entirely what you after, but they are not a cold sounding tube, pretty neutral in that respect. Where it suits me in the Vincent SA-T8 Pre. is depending what Source I use, most of my sources are on the "warmish" side. I feel for the money the Psvanes would be extremely hard to beat in Dimensionality, quietness, micro/macro dynamics, black background and resolution. They reproduce instruments and voices beautifully throughout the whole audio spectrum.

I also rolled a Quad of Psvanes 12AX7's in my DOGE 8 Phono Stage. Made only a small improvement over the supplied no-name Chinese tubes, feel that the the Doge 8 has an average Phono stage. And this may be the secret. The better the Component the better the Psvane's perform? Possibly the massive leap in performance in the Vincent SA-T8 Pre. over the supplied Tubes, might be due to that it is an outstanding Pre. Certainly the best I've heard at anywhere near it's cost and a lot more, and might be allowing the Psvanes to really shine?

Soon I'm going to roll a quad of Psvane 12AX7's in my Unison Research CDE CD Player replacing the stock Electro Harmonix Tubes. Will be interesting. Unsure how much difference rolling Tubes in CD Players makes?
