Grace Design m900 - Desktop DAC Headphone Amplifier - STILL IN BOX Tiny Box, Huge SoundThe m900 is a portable, desktop friendly headphone amplifier / DAC / preamp combo designed to give audio professionals and enthusiasts musical and transparent audio playback from USB, S/PDIF or TOSLINK sources. For small DAW studio setups, portable laptop editing or mixing rigs, or just pure playback enjoyment, the m900 provides the same analog and DAC quality as our large monitor controllers, but in a small, rugged and surprisingly affordable unit.Incredible DAC PerformanceThe m900 DAC uses the latest generation AKM 4490 chip, which features 32-bit processing and supports sample rates up to 384kHz PCM or 256x DSD. The USB interface operates in asynchronous mode allowing the m900 to be the clock master which makes the system immune to USB bus jitter. S/PDIF and Toslink inputs allow the m900 to enhance to any DAW interface with true reference quality D/A conversion, headphone monitoring and stereo speaker control.Intelligent Power Supply DesignAn intelligent power supply design allows for two power operation modes – LOW and HIGH. LOW power mode is from USB connector #1, which provides bus power along with data, allowing the m900 to operate from a single connection to your computer. HIGH power power mode is available by connecting the included 2A USB DC power supply to the USB connector #2, which provides additional power for harder to drive headphones.Superb Audio PerformanceTransimpedance amplifier topology coupled to a zero ohm output impedance driver provides headphone performance that is incredibly spacious and transparent with a tight, enveloping low end. Our latest generation crossfeed circuit rounds out the design by simulating an acoustic listening environment in the headphones. Familiar tracks become new again with surprise details, while audio production tasks like tracking, mixing and editing happen faster and easier.After many years of honing our DAC and headphone amplifier designs, the m900 distills the best of what we’ve learned in a compact, rugged and simple unit. Whether in the studio, on your desk or on the road, the m900 will bring you closer to the music you love.

Grace Design M903 Referenz Kopfhörerverstärker mit DAC + Fernbedienung aus 12/2013 OriginalverpackungImmer noch ein wirklich gutes Gerät aus der professionellen Studiotechnik

Made in collaboration with Grace Design, a company known for its incredibly accurate, transparent studio gear, the Standard DAC sets a new standard in entry-level DACs. It applies Grace Designs pro-audio expertise to a simpler, more accessibly priced model that makes a great addition to any home or office system.

Compact, capable, and easy to use, it could be all the DAC you need.

Excellent DAC/ AMP combo. Sounds really good. Accepts 1/4 and XLR connections, used both a various times with great results. NO box or instructions so you must be able to connect on your own, pretty easy though. Upgraded USB Cable (Audioquest) for connection from computer to unit, provided The only other connection is power from unit to outlet with supplied power cable. Just listened to my phone through RCA inputs and it sounded great. Usually listen via USB connection on my computer so it was good to know it works well both ways. Prefer computer setup. Great little system. Looks better in person, like me.
