Audio Research Reference Phono 3SE Phono Stage

For the vinyl connoisseur, the phono stage is not merely a component; it is the critical link to the heart of the music, a delicate instrument responsible for amplifying one of the smallest signals in all of audio. The Audio Research Reference Phono 3SE is a testament to this profound responsibility. It is the result of a relentless pursuit of sonic truth, an all-tube, fully balanced, pure Class-A masterpiece designed to pull every last nuance of information from the record groove. Incorporating the latest component technologies and circuit designs from the flagship Reference 160 series amplifiers, the REF Phono 3SE delivers a sound that is breathtakingly transparent, dynamically alive, and dimensionally holographic. It is the definitive instrument for the listener who demands nothing less than a direct connection to the original performance.

Key Features

• All-Tube, Pure Class-A Signal Path: The audio circuit is built around six 6H30 vacuum tubes (three per channel) operating in a pure Class-A, zero-feedback design for the most natural and musically engaging sound.
• Top-Level Component Technology: Incorporates the same custom-designed capacitors found in the renowned Reference 160-series amplifiers, including proprietary Audio Research-designed gold coupling caps.
• Fully Balanced, Dual-Mono Design: From input to output, the signal path is fully balanced, with separate circuits for each channel to ensure the ultimate in stereo separation and a vast, stable soundstage.
• High-Gain, Low-Noise Performance: Offers a selectable 51dB (Low) and 73dB (High) of gain, making it compatible with virtually any Moving Coil (MC) or Moving Magnet (MM) cartridge while maintaining an incredibly low noise floor.
• User-Selectable EQ Curves: In addition to the standard RIAA curve, it includes Columbia and Decca equalization curves for proper playback of vintage and non-standard pressings.
• Comprehensive Cartridge Loading: Features six selectable impedance settings (1000, 500, 200, 100, 50 ohms, and Custom) to perfectly match any phono cartridge.
• Intuitive Front Panel Control: A large, clear vacuum-fluorescent display and rotary knobs provide easy access to all functions, including loading, gain, EQ, and display brightness.
• Robust, Regulated Power Supply: A massive, highly regulated power supply ensures that each circuit stage receives immaculately clean, stable power for effortless dynamics.
• Built-in Tube Hour Meter: An integrated timer tracks the usage of the vacuum tubes, making it easy to know when it's time for a replacement set.
• Classic Audio Research Build: Housed in the iconic chassis with a brushed aluminum faceplate, custom-machined buttons, and sturdy handles, all handcrafted in Minnesota, USA.

The Soul of the Music: An All-Tube Signal Path

The REF Phono 3SE breathes life into the delicate signal from your phono cartridge through a magnificent, all-tube audio circuit. Six carefully selected 6H30 vacuum tubes form the heart of a pure Class-A, fully balanced design that operates with zero negative feedback. This approach, a hallmark of Audio Research, results in a sound that is harmonically rich, dynamically explosive, and utterly free from the grain and etch that can plague lesser designs. It doesn't just amplify the signal; it reveals the texture, color, and emotional intent of the performance, creating a listening experience of profound realism.

The Power of "Special Edition"

The "SE" designation signifies a profound upgrade in performance, thanks to the inclusion of component technologies developed for Audio Research's flagship Reference 160-series amplifiers. The most critical signal paths in the REF Phono 3SE now feature the same custom-designed, proprietary gold coupling capacitors found in its larger siblings. This infusion of flagship DNA results in a dramatic improvement in resolution, transparency, and dynamic contrast. The soundstage becomes more focused and expansive, and the music emerges from a quieter, blacker background, allowing you to hear deeper into the recording than ever before.

Total Control, Total Flexibility

The Reference Phono 3SE is designed to be the ultimate tool for the serious vinyl archivist. It offers an unprecedented level of flexibility to extract the maximum performance from any cartridge and any record in your collection. From the front panel, you can easily select between high and low gain settings and choose from six different impedance loads to create the perfect electrical match for your cartridge. Going beyond the standard RIAA curve, the inclusion of Decca and Columbia EQ curves ensures that your vintage and audiophile pressings are reproduced with the correct tonal balance, just as the recording engineers intended.

A Legacy of Craftsmanship

The Reference Phono 3SE is instantly recognizable as an Audio Research component, built to the same exacting standards the company has upheld for over 50 years. The robust chassis, with its classic brushed aluminum faceplate and substantial handles, is a testament to its "built-to-last" philosophy. Every component is meticulously assembled by hand in Minnesota, USA, undergoing rigorous testing and quality control at every stage. This is not a product designed for obsolescence; it is a handcrafted musical instrument, built to provide a lifetime of listening pleasure and a direct connection to your most cherished records.
