The Audio Research Reference Two (REF2) is a legendary, fully-balanced vacuum-tube preamplifier originally introduced in the late 1990s as a statement-level upgrade to the highly acclaimed original REF1. Revered for its immense dynamics and tonal realism, it bridges traditional tube warmth with modern audiophile precision.
Key Specifications & Design
- Tube Complement: Eight 6922 dual-triode tubes in the audio circuit, plus a tube-regulated power supply (one each of 5AR4, 6L6GC, and 6922).
- Frequency Response: 0.5 Hz to 60 kHz (+0/–3 dB at rated output).
- Distortion & Noise: Extremely low noise floor with a residual output of just (20text{ mu V}) RMS.
- Gain: 18dB (Balanced), 12dB (Single-Ended).
- Weight & Dimensions: 31 lbs (14.1 kg), standard 19-inch rack-mount width.
Core Features
- Fully Balanced Operation: Designed with high-current, electronically regulated low- and high-voltage supplies.
- Connectivity: Features 8 balanced/single-ended inputs, plus main outputs and record out.
- Remote Control: Fully motorized and remote-accessible operation, including volume, balance, input selection, and absolute phase inversion.
The Sound Signature
The REF2 is known for its incredible speed, massive soundstage, and lack of typical tube “bloat”. It handles complex, high-resolution musical passages with immense detail, allowing instruments and vocals to breathe with a remarkably lifelike presence.
