Make It Personal (and Versatile) with the Rotel DX-3 Headphone Amplifier: Fully Balanced Design Features SABRE ES9028PRO DAC, Balanced Analog Outputs, Ability to Interface with Active Speakers
At its core, the Rotel DX-3 is a formidable headphone amplifier with fully balanced circuitry, a built-in ESS SABRE ES9028PRO DAC, and sleek industrial style. The presence of a Rotel trademark — an in-house-made toroidal transformer with ultra-low-noise isolation and filter capacitors — adds to its sonic prowess.
But on the back panel, you'll also see a pair of balanced XLR analog outputs as well as a pair of RCA outputs. That means you can run a network or CD player through its DAC, and hook DX-3 up to a preamplifier or processor if you choose to make it a temporary or permanent part of your system. Optical, coaxial, PC-USB, and Bluetooth digital inputs further expand its versatility, as does its ability to interface with active powered speakers — giving you a compact albeit audiophile-grade combo.
Able to play music up to 32-bit/384kHz PCM and 11.2MHz DSD from the USB input, 24-bit/192kHz from the coax/optical, and aptX HD Wireless Bluetooth, DX-3 drives all types of headphones with ease, control, power, and definition. Balanced and single-ended headphone inputs on the front panel offer user-friendly convenience and process signals with extremely low distortion, fast speed, and natural purity.
Roon-Tested and measuring only 8.5 x 2.75 x 9.75 inches (HWD), DX-3 also touts a full-color graphic display, extruded aluminum remote control, and the engineering expertise that has made Rotel synonymous with high-value, high-performance gear.
