Accuphase :: C-27 Stereo phono amplifier

The analogue phono record is experiencing a quiet boom among discerning music lovers. It goes without saying that a phono equalizer of high quality is essential to extract the enormous richness of sonic information engraved on vinyl records. Furthermore, the selection of tonearm, cartridge and other parts of the playback system requires a thorough understanding of audio fundamentals. This is a field where some investment of time and effort can yield immensely satisfying results.
Accuphase has gained considerable expertise in designing and building phono equalizers, either integrated in preamplifiers or available as option plug-ins (AD-2810 and AD-20).
In response to the wishes of audiophiles worldwide, we have now developed the C-27 as a high-end standalone phono equalizer amplifier, capable of exploring the possibilities of the analogue disc to the fullest.
