Sounds like the hiss is coming from the tubes. I would order a set of tubes direct from Audible Illusions in Florida. Takes about a week to get them and they are perfectly matched for your preamp. There is no second guessing.
Sovtek 6N23P-EV / 6H23P-EB NOS for AI Modulus 3A?
I need to replace the tubes of my Audible Illusions Modulus 3A phono stage. As I live in Europe I prefer to order them here from Tube Amp Doctor (TAD). TAD recommends their own TAD 6922 / E88CC Premium Selected or Sovtek 6N23P-EV / 6H23P-EB NOS.
Has anyone experience with Sovtek 6N23P-EV / 6H23P-EB NOS? Are these similar to the 6H23n-EB/6922 ones The Tube Store or Upscale Audio recommends?
Thanks much for your input
