Hybrid Circuit Design Combines Power with Tube Warmth

The Roma 37DC+ incorporates a hybrid circuit design that uses a Class D ICE POWER module in the output stage, providing an impressive power output of 450W into 4 ohms or 250W into 8 ohms. This high efficiency meets the refined detail of a 6DJ8 tube input stage, capturing the warmth and naturalness of tube sound while maintaining the dynamic range and speed of Class D amplification. This combination results in a sound that’s airy and musical, emphasising the purity of vocals and instruments for a breathtaking listening experience. With an input sensitivity of 200mV, the Roma 37DC+ achieves full output without sacrificing any of the intricate details that make music sound live.

Advanced Digital and Analogue Connectivity for Versatile Playback

Equipped with a range of inputs, the Roma 37DC+ is designed to support various digital and analogue sources, making it a versatile centrepiece for any audio setup. Two line-level analogue inputs and one phono input provide connectivity for both traditional audio sources and vinyl turntables, featuring a Moving Magnet (MM) phono stage that ensures smooth and high-quality playback for vinyl enthusiasts. The digital side features a USB-B input compatible with Windows, macOS, iOS, and Android, as well as a Toslink optical input, both of which enable high-resolution playback up to 32-bit / 384 kHz and DSD 5.6 MHz over USB. This wide compatibility allows users to connect a range of devices, from smartphones to high-resolution digital audio players.

Precision Digital-to-Analogue Conversion for Enhanced Sound Quality

Central to the Roma 37DC+’s performance is the AK4495SEQ Digital-to-Analogue Converter (DAC), a 32-bit, 768 kHz DAC renowned for its precision and low distortion. Capable of handling high-resolution files up to 24-bit / 192 kHz over optical and 32-bit / 384 kHz over USB, this DAC provides a beautifully articulated sound with rich detail and texture. The DAC’s accurate sound stage and tonal depth transform even complex recordings into an immersive experience, capturing each subtlety with precision.

Robust Power Handling and Thermal Efficiency for Uninterrupted Performance

The Roma 37DC+ amplifier is built to handle substantial power loads, drawing up to 1000W to ensure consistent performance across demanding sessions. Designed with Class D efficiency in mind, the unit not only maximises power but also reduces heat generation, allowing for prolonged usage without compromise. With a signal-to-noise ratio above 90 dB, it delivers a clean, focused sound even at high volume levels, maintaining a low noise floor and capturing the finest nuances in recordings.

Elegant Remote Control with Comprehensive Functionality

The Roma 37DC+ comes with an anodised black aluminium remote control that operates on the RC5 infrared protocol, offering precise control over volume, input selection, mute, and standby functions. Designed with the same attention to detail as the amplifier, this remote ensures that users can make adjustments seamlessly, adding a layer of convenience to the high-fidelity experience. Powered by two CR2032 batteries, the remote is both durable and efficient, providing reliable functionality from across the room.
