DESCRIPTION:

   The Model One---A New Generation of Integrated Amplifier

  Through some six years of painstaking research and development and exhaustive listening trials the Model One by NSR---a new Generation of Integrated Amplifier featuring a digital interface plus a pure analog is now here. The Model One redefines the integrated amplifier like no other. As the very first NSR Integrated Amplifier, the Model One defines the state of NSR technical art and the sum of the brand’s knowledge and design skills.

  High Level of Reproduction Realism

  Featuring two ESS9018 chips housed in a robust DAC module and a dedicated HDMI interface to receive the native I²S and DSD music data, the Model One is capable of hardware decoding the native DSD files--including DSD64, DSD128, and DSD256; the USB input reliably and accurately receives audio data in PCM format at up to 32-bit/384KHz while offering supports for virtually any of your high resolution music format including DXD files.

  Unsurpassed Musical Purity

  NSR has been dedicated to the uncompromising art of sound, with the guiding principle of musical purity above all else. Key to the exemplary purity and exacting precision of the Model One is that the digital section and analog section use independent power supplies to optimize power for the cleanest, most stable signals possible. Higher frequency digital noise may propagate through signal cables to add further sonic loss. For this reason, the Model One offers a discrete, direct-coupled, and punishingly short signal path, and the minimum cables and cords are used within the space saving chassis. NSR engineers spare no expense sourcing the best possible materials from around the world, and take painstaking effort hand-matching each transistor up to a merciless standard. Featuring a low distortion, high-speed, and wide bandwidth design, along with meticulously-selected 0.5PPM oscillators, the proprietary NSR signal circuit cancels virtually all the distortion and noise while maintaining a THD less than 0.03% at full power output. With a staggering 85v/uSec slew rate and a 650kHz/-3dB bandwidth, the Model One is filled to the brim with everything you need to get every last musical note and nuance of your records---including some you may have never heard before. The result is a remarkable retrieval of ambient detail that other integrated amplifiers simply cannot reach.

  Industrial-grade Chassis  

  The peerless craftsmanship of NSR is evident in every aspect of the Model One. Housed in an industrial-grade, steel chassis, the  Model One features extremely high precision, to exceedingly low tolerances. The shielded steel box protects the internal components and other circuits against electrostatic and magnetic interference and the extraneous dust and moist while offering an identical operating condition regardless of temperature and humidity.
