The Oppo 105 For true music lovers, nothing equals the warmth, dynamic range and fidelity of vinyl records. Therefore, a critical component of every audiophile’s vinyl playback system is the phono preamp.
Due to the extremely small signal produced by a phono cartridge a good phono preamp is one of the most difficult pieces of audio equipment to produce. We’ve spent 10 years developing and refining our Exception Phono preamp to meet our standards of performance.
Words are inadequate to explain the Exception Phono. Like the rest of our equipment, you have to hear the Exception Phono to fully appreciate what it does.
