The Music First Audio Baby Reference Pre has no resistors inside but a high quality attenuation transformer with enough taps to comfortably control the volume level.
A simple recording of voice and acoustic instruments and from the first note to the last the MFA lets the music flow. The midrange cries out for attention with a naturalness that is only to be found on true high end preamps, most of which cost a lot more than the MFA.
It brings detail and delicacy, and has enough power to be utterly convincing. The fact that absolutely no background noise exists because the MFA has no electronics, adds to the excellent performance.
