HA-TL II | developed to be the cleanest amp we could build. Straight wire theory. Extremely low noise. Transformerless design offers a straightforward signal path (with no superfluous circuitry to encumber) or possibly distort the imaging of the capsule's character. What goes in is what comes out - only louder.
