To @dhcod I’m looking back over your original post. Something showing people running the Herron tube preamp with the Herron mono amps and the SIT3 you mentioned. https://www.stereonet.com/forums/topic/524309-fs-stunning-combo-herron-vtsp-3a-preamp-and-firstwatt-sit-3/
Your original comment > "Herron had the bass but was otherwise unsatisfying. "

Preamp:
What preamplifier / line stage were you running with the Herron or SIT3 amps?
