@kennesawjet I am not familiar with your particular preamp and couldn't locate any information googling herron v1.
If it is a tube preamp you know their tubes often loose fidelity slowly over time. If it is a tube pre and you haven't changed tubes in a while I think it may make a marked difference for the better. If by chance it uses 12ax7, as mine does, you might consider trying 5751 tubes in the line stage (not phono stage). GE 5751 black plate triple mica tubes are affordable and very good.
Of course if your preamp is SS, forget the above.
