About the Accession MM
The Graham Slee Accession MM is a compact phono preamplifier for moving magnet and moving iron cartridges.

It also provides both fixed and variable outputs, allowing it to function as a phono stage or as a direct volume-controlled preamp for a power amplifier. The unit is powered externally by the PSU1 linear power supply.
