The Rotel DX-5 Stereo Integrated Amplifier is a new addition to Rotel's desktop audio product line, providing an integrated amplification solution alongside digital-to-analog conversion and versatile connectivity. This product follows the release of the Rotel DX-3 DAC/Headphone Amplifier, expanding Rotel's offerings in the compact audio component category.
The DX-5 incorporates a Class AB amplifier, delivering a specified power output of 33 Watts per channel into a 4-ohm load and 25 Watts per channel into an 8-ohm load. The amplifier section utilizes a toroidal transformer, designed and manufactured in-house by Rotel, and high-current transistors. According to the manufacturer, this configuration aims to provide clear reproduction across the frequency spectrum, with specific emphasis on high-frequency clarity, midrange detail, and bass definition.
Digital audio processing within the DX-5 is handled by the ESS ES9039Q2M Sabre DAC chip. This DAC is capable of supporting high-resolution audio formats. The reported performance specifications for the digital section include a Signal-to-Noise Ratio (SNR) of 100 dB. The overall frequency response of the amplifier is stated as 10 Hz to 100k Hz with a tolerance of ±0.19 dB.
The DX-5 offers a range of input and output connections to accommodate various audio sources and system configurations:
- HDMI ARC (Audio Return Channel): This input allows for direct audio connection from televisions equipped with ARC functionality, simplifying the integration of TV audio into a stereo system.
- Subwoofer Output: A dedicated output is provided for connecting a powered subwoofer, enabling the creation of a 2.1 channel audio system with extended low-frequency capabilities.
- Headphone Output: A front-panel 3.5mm jack allows for private listening through headphones.
- PC-USB Input (Type B): This USB Audio Class 2.0 input supports high-resolution PCM audio up to 32-bit/384kHz and DSD audio up to DSD 4x (11.2MHz). The manufacturer indicates that driver installation may be necessary for optimal performance with certain operating systems.
- Digital S/PDIF Inputs (Coaxial and Optical): Two digital inputs, one coaxial and one optical, support linear PCM (LPCM) audio with resolutions up to 24-bit/192kHz.
- Bluetooth Connectivity: The DX-5 includes Bluetooth wireless connectivity, supporting the aptX HD and AAC audio codecs for higher-quality wireless streaming from compatible devices.
- RCA Analog Input: A single pair of RCA connectors allows for the connection of analog audio sources.
The Rotel DX-5 has been certified as Roon Tested, indicating that it has been tested and verified to work seamlessly with the Roon music management and playback software. The amplifier features a precision volume control with 0.5dB increments and an input sensitivity of 680 mV. The front panel incorporates a full-color Thin-Film Transistor (TFT) display for user interface and information display. The unit is supplied with an aluminum remote control.
The physical dimensions of the Rotel DX-5 are 215 mm (width) x 76 mm (height) x 251 mm (depth), with a net weight of 4.1 kg (9.1 lbs). The front panel height is 70 mm. The amplifier is available in two finish options: black and silver. The power consumption is rated at 80 Watts, with a standby power consumption of less than 0.5 Watts.
