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?

This is a topic I’ve been following for awhile. Although I’m not an EE, I do know I hear what I believe is tube rush from my Aesthetix Rhea eclipse phono pre. I’ve tried to ensure good connections from the cartridge all the way to the pre. I also found I had some RFI or EMI from a google mesh wireless extender that was positioned too close to my TT/cartridge.

But I can say unequivocally that going to ultra low noise 12AX7 NOS tubes (amperex) in V1 and switching from 6922 to 7308 ultra low noise amperex made a big difference. It did not eliminate but the rush but it is now very tolerable. And with the low-noise telefunkens in the other tube slots, a very very enjoyable sound.
