SPL Audio Phonos

Phonos is a preamplifier for record players using either moving magnet (MM) or moving coil (MC) cartridges. The equalization curve is according to RIAA and suitable for all vinyl records since 1954. This phono preamplifier is equipped with the best sounding capacitors and built after the legendäre Douglas Self design. The control parameters are adjustable on the front and therefore always accessable to make the search for the best sounding setting a fun experience.
