The m920 High Resolution Monitoring System provides wide open, musical audio playback performance for discerning audio professionals and connoisseurs. In this world of endless distraction, the m920 is designed to enable limitless engagement. Whether you are perfecting the details of a mix or blissfully drifting around your favorite DSD downloads - the resolution, detail and immediacy that occurs with the m920 at the center of your system will place you deep in the heart of the music.
Building on our 15 years of experience designing reference playback equipment, the technology in the m920 is as evolved as it is refined. The new, world-class M Series 32-bit Sabre DAC provides an astonishing improvement in digital performance, delivering up to 32bit/384kHz PCM and 64x and 128x DSD playback. This DAC allows the user to select between 3 different digital filter response curves: fast, slow and minimum phase – which helps tailor the DAC section to personal tastes. Third generation s-Lock PLL circuitry improves jitter rejection without the use of sample rate converters. Asynchronous USB playback allows bit-perfect audio playback from your computer.
Analog design is carefully executed to ensure signals are rendered perfectly regardless of what type headphone drivers, amplifiers or speakers are being used. High current transimpedance output amplifiers can easily drive 8 ohm loads, making the m920 a perfect choice for even the lowest impedance headphones. Only the highest quality 0.5% metal film resistors are used throughout and there are no electrolytic capacitors in the signal path. Sealed gold contact relays are used for all signal switching.
We began building compact headphone amp / DAC's over 15 years ago. So the m920 represents lots of refinement with the addition of years of real world customer feedback. We have thousands and thousands of happy owners of these products. While there are countless more affordable derivative devices available now, a careful examination of the refinement, performance and design of the m920 reveals a product that is a little bit more expensive but a lot more value. We design and build everything in the USA, and back it up with our unrivaled 5 year transferable warranty. Our customer service is second to none, with customer satisfaction to match.
With several IR remote control options, including the Grace Design remote, or the apple remote and iOS / Android via Logitech Harmony, DSD128 playback, and beautiful, stable, open audio performance, the m920 will grace your system and engage you with your collection like never before.
With two sets of studio monitor outputs, two headphone jacks, a wide array of input options and deep calibration options, the m920 is the perfect choice as your svelte, clean and perfectly appointed monitor controller.
