    Mark Levinson 380S Preamp

    I use this preamp which drives a Audio Research D400MKII
    power amplifier for adjusting the levels of my Magneplanar
    Tympani bass panels. The volume control has extremely
    fine volume adjustments of . 1db. and one can obtain an
    excellent balance. The output impedance is under 6 ohms
    and can easilly drive several power amplifiers. Having
    balanced inputs and outputs is also a big plus giving one
    a great signal to noise ratio (dead silent). Having a
    rotary subwoofer with bass down to 1 hz requires a preamp
    with very low frequency response and the Mark Levinson
    meets this requirement.
