Audio professionals and music enthusiasts in need of a professional-grade headphone monitoring system will be impressed with this B&H Kit, which combines the Neumann NDH 20 Headphones with the Grace Design m900 Compact, Portable Headphone Amp, DAC, and Preamp to create a turnkey monitoring solution for mixing, tracking, and critical listening.
Designed for tracking, mixing, and critical listening, the Neumann NDH 20 Headphones offer a closed-back circumaural fit as well as a delineated sonic image. The headphones make use of 38mm drivers that employ a high-gauss neodymium magnet to ensure a response devoid of distortion and coloration. They provide a frequency response of 5 Hz to 30 kHz.
Many other closed-back headphones supply nasty resonances in the midrange, which make it difficult to make accurately informed mixing decisions. This pair was designed to avoid such pitfalls to give you a sound and soundstage similar to that of Neumann's line of studio loudspeakers.
The NDH 20's adjustable headband is constructed from steel while the earcups are fashioned out of lightweight aluminum. For earpads, you get cushioning memory foam that supplies hours of comfort.
When you're done with the headphones, simply fold them up and put them in a soft-cloth bag. Two detachable cables are included, one straight and the other coiled. A 1/4" adapter is also supplied.
- Linear sound balance similar to Neumann's acclaimed studio monitors
- Isolation allows working in noisy environments
- Transparent sound
- Long-lasting comfort
- Easy transportation thanks to foldable design and soft cloth bag
The Grace Design m900 is a compact, portable headphone amplifier, DAC, and preamp, well suited for audio professionals, music enthusiasts, or anyone looking for transparent playback from USB, S/PDIF, or TOSLINK sources. For small DAW setups, the m900 provides the same analog and DAC quality as Grace Design's large monitor controllers, but in a rugged, portable, and surprisingly affordable unit.
The heart of the Grace Design m900 features the latest generation AKM 4490 chip, which includes 32-bit processing and support for sample rates up to 384 kHz or DSD256. 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 enhance any DAW interface with true reference-quality D/A conversion, headphone monitoring, and stereo speaker control.
The intelligent power supply design allows for two power operation modes, Low and High. Low power mode is derived from USB connection 1, which provides bus power along with data, allowing simple operation from a single connection to a computer. High power mode is available by connecting the included 2A USB DC power supply to USB connector 2, which provides additional power for high-impedance headphones.
The Grace Design m900 utilizes trans-impedance amplifier topology coupled to a zero-ohm output impedance driver for headphone performance that is spacious and transparent with a tight, enveloping low end, while the latest generation cross-feed circuit rounds out the design by emulating an acoustic listening environment in the headphones. The Grace Design m900 ships with a 2A USB power supply and two USB Type-B mini-cables (6' and 10'.)
