The DP-Drive is a docking station for the DP-01 MM and DP-04 MM / MC boards and comes with separate precise power regulator power supply. Regardless of the board used, the DP-Drive is a complete RIAA phono stage. Do not be fooled by the low price; it offers the best of Densen design. In one word: Musicality.
The DP-01 MM stage is for B-200 and the old Densen products DM-10, DM-20 & B-100. The DP-03 is an MM board for the B-110, B-130, B-150 & B-250. The only difference between the DP-01 and DP-03 is the physical shape, which allows them to be used with different Densen products.
Despite of the modest price of these two boards, it will offer you a world class RIAA when mounted in any Densen amplifier. Due to the technical design, the DP-03 and DP-01 work with all MM cartridges on the market, and actually do so with an outstanding sound quality.
