It is normal (acceptable for me) hiss. After replacement of my unit, it arrived with JJ 12AU7 tubes. And it was exactly like you said with my ZMF Auteur hiss was after 3 oclock, but in my situation on only in XLR output and high impedance position. 1/4 was quiet in all impedance position. I have done some tube rolling 12AU7, switched to RCA input (XLR -too much gain), as a source switched from PC to laptop Apple MB Pro15 (less USB ground interference), used Ifi USB signal cleaner, DAC Cambridge Audio 851D and now it is dead silent.Its a new one it come with 12au7 JJ tube. first I got hiss when I use my PC as a source then I try with streamer all hiss disappear with my hifiman he1000se but Verite I hear hiss only volume at 3Oclock or more.
BTW: I am using now Tesla ECC802S and KT88 Gold Lion UK made
