Top 10 Grace Design Desktop Dac Headphone Amplifier

Grace Design’s m900 takes the stunning detail and flawless imaging of their flagship m920 headphone amplifier and packs it into a portable, bus-powered unit. But just because the m900 is portable, doesn’t mean it’s lacking. Experience jitter-free computer audio playback, with support for up to 32-bit/384kHz PCM and 256x DSD. Dual zero-ohm output impedance headphone outputs deliver spacious and transparent performance, while stereo unbalanced analog outputs make connecting to your stereo monitor system easy. Either way, four different DAC filter settings provide personalized playback. At GearNuts, we appreciate the m900’s simple setup menu and easy-to-read 7-segment LED display, and its large rotary encoder makes volume control and menu navigation a breeze.

The Monolith liquid spark is a compact headphone amplifier developed by Alex Cavalli for Monoprice. It provides everything people have come to expect from a Cavalli design. It uses dual 18 V filtered power supply Rails to produce wide voltage swings for additional headroom. The spark offers plenty of power at 1300MW RMS into 50ohms (per channel), with very low distortion, and switchable gain.

Tired of straining to hear the headphones? The HP4’s four 130 mW headphone outputs are clear, clean, and screaming loud, all packed in a compact, 1/3U chassis. Features include balanced L/R line inputs and outputs, global mute, overall level control, and sum to mono. The line outputs can feed another HP4 or an HP60.

If you’re tracking more than one musician at once, or if everyone in a group wants to listen to a playback, you need a monitor distribution system. The compact, flexible PHA40 can power up to four pairs of headphones and up to four independent volumes. Grab this super-compact amp during your sessions to power practically any headphones–four of them at the same time, to be exact. This allows four people in your studio to listen to the main mix while recording and each listener can determine their own volume level using the dedicated output level controls. The PHA40 contains 4 high-power stereo amplifiers that maintain the highest sonic quality even at maximum volume levels. These ultra-low-noise operational amplifiers are included for outstanding audio performance.

The Sennheiser HDVD 800 is a premium performance headphone amplifier with built in digital to analog converter. It features balanced symmetrical audio signal processing from input to output delivering extremely high resolution and ultra-low harmonic distortion. A precision Burr-Brown digital/analog converter (DAC) converts digital audio sources into analog signals with a resolution of 24 bits and a sampling rate of up to 192 kHz. The HDVD 800 also has an asymmetrical RCA input that converts incoming signals for symmetrical processing by the amplifier. Digital sources are connected to the rear of the unit via XLR (AES/EBU), optical, coaxial (S/PDIF) or USB input. All digital inputs accept signals up to 24 bit at 192 kHz. The fixed level balanced (XLR) outputs are matched to the selected input allowing you to use the audio processing capability of the HDVD 800 when connected premium audio systems. Designed and manufactured in Germany, this transparent and neutral solid-state amplifier is a perfect match with any of our critically acclaimed audiophile headphones.
