I can certainly identify with this topic and the advice so far has been spot on consistent with my experience. I too have a Herron VTPH-2A and noticed tube rush only a foot or so from the speaker when volume is up quite loud and BEFORE needle touches the vinyl. I have found a bit of success (in my quest to lower the phono noise floor) by moving from a 0.3mV cart to a 0.5mV and by dialing gain and loading through a Zesto SUT. I've had discussions with Roger Modjeski about possible noise reduction using his SNL tubes (at ~$100/ea) in the 1st gain stage of the Herron. He thought it might lower the noise floor a few dB but he said it's hard to say. Haven't pulled the trigger on new tubes yet.
Phono Preamp Tube Rush
Is there such a thing as a tube phono stage that doesn't have tube rush? Is it just an inherent weakness of that type of pre or is it some combination of cartridge gain and preamp gain? I went from a silent solid state ASR Basis Exclusive to a Herron VTPH-2A (new home with space limitations) and now I'm using a Hagerman Trumpet with my Decca London Super Gold. Both the Herron and Hagerman have tube rush. The Hagerman beats the Herron in my setup and it really sounds incredible but in quiet passages and between songs, there's that hiss at high-medium and high volume. It's just there. No combination of new tubes, new cables, etc changes this fact. Same with the Herron. Anyone having a different experience with a tube phono preamp?
