Audio Research

Reference Phono 3

When Audio Research was founded in 1970, analog vinyl playback was the de facto music source of the time. Audio Research has either incorporated or built stand-alone phono stages since the very beginning, and has continuously provided phono preamplification, even during the height of digital music. The Reference Phono 3 is the next advancement of analog playback. **Price In USD**
