Rotel DX-3 Review: Compact Headphone Amp with Hi-Fi Punch
Affordable Power for Serious Headphones
The Rotel DX-3 is a compact yet capable headphone amplifier designed for audiophiles who demand premium headphone listening without a rack full of gear. Whether you're using planar magnetic headphones or sensitive IEMs, the DX-3 promises refined, transparent sound with enough power to handle demanding loads. In this review, we explore the design, performance, and value offered by this sleek little amplifier from Rotel.
Design and Build
The DX-3 follows Rotel's clean industrial design language, with an all-metal chassis, machined front panel, and tactile volume control. Its small footprint makes it perfect for desktop setups, while its weight and finish lend it a feeling of durability and refinement. Available in silver or black, it matches most hi-fi aesthetics effortlessly.
Ventilation is subtly integrated, and there’s minimal branding—just an LED indicator, a smooth volume dial, and a 6.35mm headphone jack on the front. All connections are solid, and the build inspires confidence.
Amplification and DAC
Under the hood, the Rotel DX-3 features a high-current amplifier circuit designed to drive headphones from 16 ohms to 600 ohms. It’s equipped with a dedicated ESS Sabre DAC chip that supports up to 24-bit/192kHz over USB and coaxial inputs.
The output stage is tuned for neutrality and control. There's no artificial warmth—just accurate, musical sound. With sensitive headphones, it remains quiet and hum-free, while with power-hungry planar headphones, it delivers punch and headroom that rivals larger desktop units.
Inputs and Compatibility
The DX-3 offers USB-B input for connecting to computers, along with coaxial and optical digital inputs for use with CD transports or streamers. There's also an RCA line input for analog sources, giving it excellent flexibility for a device of this size.
It supports Windows, macOS, and most Linux distributions without special drivers. Whether you're using Roon, Audirvana, Spotify, or TIDAL, the DX-3 is plug-and-play—and ready to reveal the nuances in your favorite recordings.
