REFERENCE PHONO 10 PHONO PREAMPLIFIER Vinyl record playback has been an integral part of Audio Research since our founding in 1970. Think back to the great phono stages built into the defining preamplifiers of their day, among them the SP3, SP6, SP8, SP10, and SP11. Even after the introduction of the compact disc in 1982, phono sections remained a revered part of our preamplifiers. The firs...[more]

Power Supply Highlights Positioned between the two audio channels, the power supply makes use of extensive electrical and magnetic shielding to keep radiated interference out of critical preamplifier circuits. Internal line conditioning circuitry filters RF noise on the AC power and compensates for asymmetric power waveforms and DC on the mains. Power for the preamplifier stages comes from ...[more]

The Virgo III is an evolutionary step from the former Virgo II and like its predecessor the new Virgo III uses a separate power supply for better isolation and lower noise. Compared to its predecessor, the Virgo III will provide improved remote control operation, smoother operation of front panel knobs, and new internal circuitry that allows a quicker warmup time for virtually instantaneous pea...[more]

The DiaLogue Premium Preamplifier contains: -New front-end circuitry. The DiaLogue Premium uses three 12AU7 tubes per channel.  The result is even lower distortion and increased bandwidth.  The change in dynamic range is stunning!  Output impedance is lowered to only 256 ohms, allowing it to mate with every amplifier on the market that we know of, even some older Pass Labs mo...[more]

This preamplifier is enclosed in a case with extremely restrained lines. Its front plate is in polished aluminium. ...[more]

DPL2   This preamplifier matches black with gold : the restrained lines of the case in black openwork metal, its front plate in polished aluminium, or as an option, in gilded brass as on the JPL. Sombre and luminous, mat and brilliant, the DPL 2 combines visual harmony with an insistant discretion. The signal processing is carried out by 2 double triode tubes, ECC82 and ECC 83, whi...[more]

Like the DAC8, the DSPre offers the following:• Five digital inputs, including USB 2.0HS, AES/EBU, RCA, BNC, andToslink®, all of which are capable of decoding 24 bit/192k files.• Asynchronous USB.• Utilizes quad “monoblock DAC” architecture with dual low jitter mastercrystal oscillators to eliminate decoding and quantization errors, increasethe dynamic range, and ...[more]

Often overlooked, the preamplifier is a critical component in the signal chain. A small signal must be carefully amplified without damaging the ephemeral staging and dimensional components of the music. The Evolution 202, using a combination of advanced technologies and inspired design, elevates this task to an art form. Music emanates from an expanse that outlines the recording venue, transpor...[more]

The Evolution 222 brings the advanced technologies and inspired design of the Evolution 202 to single chassis format. Often overlooked, the preamplifier is a critical component in the signal chain. A small signal must be carefully amplified without damaging the ephemeral staging and dimensional components of the music. Heard through the Evolution 202, music emanates from an expanse that outline...[more]
