The Lambda line was born out of the Sigma research and the main agenda was to make a headphone that sounded like the SR-X Mk3 yet had more bass and treble extension with a more natural soundstage.
so would the normal bias lambdas be considered superior? maybe I should pose the question like this. If I had a lambda normal bias, a lambda signature, and a sigma something, all the same price, which one is preferred. if they are different in sound signature, how so?
I'm just trying to figure out what to look for, and all these model numbers, old and new, is confusing.
