Volleyguy,
Assuming that your Psvane 12ax7 tubes meet spec, you'll continue to hear improvements. After 50 hours, you'll hear a more open midrange and particularly extended bass and high frequency response. I have yet to hear a better high end from any NOS 12ax7 than what these new Psvanes provide.
