USD$350 is a strong bargain for a used Soundsmith MMP4 phono preamp, sitting well below the typical used market where these units rarely dip under USD$500–USD$600. New MMP4s retail around USD$800, so even a conservative 25th percentile on the used ladder pushes past USD$450, making this listing an excellent value.
The MMP4 is a respected, precision-engineered stage that handles MM, MC, and high-output MI cartridges with 43 dB of gain, ultra-low distortion (0.004% THD), and a clean –92 dB noise floor. Its robust aluminum chassis, accurate RIAA equalization, and globally compatible 24V DC supply (US/EU plugs included) make it a versatile, reliable upgrade for any vinyl setup. At USD$350 with no listed condition issues, this is a genuine buying opportunity for enthusiasts seeking premium phono performance without the new-unit price.

Soundsmith traces its roots to Peter Ledermann, a veteran audio engineer with over 50 years of experience, whose career spanned design roles at RAM Audio and Bozak speakers, followed by stints at IBM's T.J. Watson Research Center. Leaving corporate life in 1991, Ledermann transformed his earlier audio mentoring venture, The Soundsmith, into a full-fledged manufacturing company based in Peekskill, New York. For more than 40 years, he has served as president and chief engineer, channeling a lifelong passion for science and sound into innovative analog solutions.
The brand specializes in handcrafted phono cartridges, renowned for their moving-iron, fixed-coil designs that deliver exceptional sonic detail and value. Models like the Aida high-output cartridge exemplify Soundsmith's commitment to precision engineering, with customizable options such as ruby cantilevers. While not venturing into amplifiers, speakers, or digital gear like DACs, their focus remains laser-sharp on elevating vinyl playback through superior cartridge technology.
Positioned as a niche boutique in the high-end market, Soundsmith earns acclaim among discerning audiophiles for its artisanal quality and Peter Ledermann's personal touch, including ties to his charity DirectGrace Records. Reviews from outlets like Stereophile highlight its consistent excellence, making it a go-to for vinyl enthusiasts seeking transformative performance without mainstream hype.
