Brand: Soundsmith


** Newly Updated and Improved! **

An upgrade in quality does not have to deplete your wallet.

The Soundsmith MMP & MCP preamps are revolutionary
designs for their price – and the comments we get at each hi-fi show prove it.
These preamps are what we use to demo our cartridges at all our shows even our
high end cartridge designs –

Each hand – made preamp circuit is housed in a high quality
aluminum case, powered by an external DC power supply, with easy to set up
instructions. All amplifiers have extremely accurate RIAA equalization

Our MMP4 is a more cost effective way to enjoy your high
output MC, MM or MI cartridge. Its design is based on our highly praised MMP3,
and the specs and sonics make it a great value. It features 47K loading and 43
dB of gain.

Employing very high quality components, the MMP4 assures
noise free and ultra-low distortion to allow unfettered enjoyment from your
treasured vinyl collection. The MMP4 and MMP3 have been favorably demonstrated
against preamps costing $2000 – $4000 with surprising results… and compliments
to Soundsmith.
