Synthesis Roma 79DC Valve Phono Stage

Synthesis Roma 79DC Tube Phono Stage: Precision and Warmth for Vinyl Aficionados

The Synthesis Roma 79DC Tube Phono Stage is a meticulously engineered high-performance phono preamplifier tailored for discerning vinyl enthusiasts. Available in five elegant finishes—Wood, Black, Dark, Aluminium Silver, and Aluminium Black—the Roma 79DC combines tube warmth with precise componentry to produce a rich, immersive sound. Designed to handle both MM (Moving Magnet) and MC (Moving Coil) cartridges, this phono stage brings unprecedented flexibility and pristine analogue sound to any high-fidelity audio system.

Dual-Tube Gain Stage for Audiophile-Grade Fidelity

At the heart of the Roma 79DC are two high-quality ECC83/12AX7 tubes and one ECC82/12AU7 tube, housed in a precisely controlled gain stage. This tube combination brings smooth, warm audio reproduction that’s ideal for vinyl. The ECC83 tubes amplify delicate signals from both MM and MC cartridges with a lush, dynamic tone, while the ECC82 on the output stage maintains a low output impedance, enhancing signal integrity and preserving sound details. This dual-tube configuration ensures a velvety, detailed soundstage that captures the richness of analogue records.

Precision-Tuned MM and MC Gain for Versatile Cartridge Compatibility

The Roma 79DC offers gain settings of 40 dB for MM cartridges, 60 dB for standard MC, and 65 dB for high-gain MC cartridges, making it adaptable to various vinyl playback requirements. The low-noise JFET transistor in the MC input stage has a dedicated power supply with comprehensive filtering, isolating and reducing interference for a clean, high-quality signal. With this flexibility, the Roma 79DC optimises signal strength, allowing the subtleties and depth of both MM and MC cartridges to be fully realised.

Customisable Cartridge Load Settings with Front-Mounted Selector

A key feature of the Roma 79DC is its user-friendly front-mounted knob for adjusting cartridge loading, with selectable capacitance for MM and impedance for MC cartridges. Displayed on an intuitive front-panel LCD, this configuration enables listeners to match the phono stage settings to their cartridge’s specifications with precision. MM capacitance options range from 47KOhm with eight capacitance settings (47 to 420 pF), while MC impedance settings span from 22 to 1000 Ohms. These customisable options make it effortless to fine-tune cartridge loading for enhanced playback accuracy and sound quality.

Shielded Power Transformer and High-Grade Capacitors for Noise-Free Performance

The Roma 79DC’s oversized, shielded power transformer reduces external electromagnetic interference, ensuring stable and quiet operation. High-quality metallised polypropylene capacitors are strategically positioned to manage the audio signal circuits, minimising distortion and delivering an exceptionally clear sound. These components, in conjunction with a fully regulated multi-stage power supply, support the DAC’s high-fidelity performance by preserving audio purity, even at higher volume levels.

Compact, Durable Design with Versatile Power Compatibility

Built to integrate seamlessly with any audio setup, the Roma 79DC measures 260x380x95 mm and weighs a solid 5 kg, giving it a durable, well-built feel. This unit is compatible with multiple voltage settings (117/230/245 VAC) for flexible international use, and features a power consumption of 30W max, ensuring efficient energy use without sacrificing performance.

The Synthesis Roma 79DC Tube Phono Stage embodies Synthesis’s dedication to audiophile quality, enabling vinyl lovers to explore and appreciate the full range of analogue sound. Its innovative design and precision-tuned components elevate vinyl playback to an exceptional listening experience, making it the ultimate addition to any serious vinyl setup.
