Don’t know the Lamm but own the Herron. Not sure if what you are looking for is a euphonic tube sound with added warmth but you won’t get that with the Herron. You will know you are listening to tubes because of the harmonic rightness and the air and space around the instruments and voices. But you won’t hear any stereotypical tube colorations or tube induced noise. Just a high level of purity and impeccable timing. And, as others have mentioned, Keith!
