Never had the opportunity to audition a Herron preamp but I do own a Backert Labs Rhythm 1.3 . Please contact them for a loaner before you make a decision. Andy is a great guy. I find that my Backert has a control over bass notes that makes a sonic difference in my system. Please check my avatar.
Backert Rhumba 1.3 vs Herron Reference?
Has anyone ever been able to directly compare the Backert Rhumba 1.3 to a Herron 360 reference preamp?
