N20

The N20 caching music server / streamer provides the fidelity, features and flexibility the digital audiophile will find attractive and meaningful. A significant advantage is that the N20 contains two empty storage bays. This allows you to customise storage to best meet your budget and intended use. For example, these days many music lovers listen exclusively to streaming content. Therefore, no internal storage is necessary (although it can be easily added at any time if desired). Have a modestly sized music collection? Install an inexpensive 2TB HDD. Own a massive music library? Opt-in for 2 SSDs or HDDs. Fully loaded, the N20 is capable of accommodating an incredible 16TB of solid-state storage!

An Intel Quad Core CPU is used to support the most demanding digital file codecs including Native DSD512 transmission. All file types and formats are handled by this processor with exceptional ease and aplomb. Our latest generation SPDIF digital output suite employs transformer isolated grounding for the lowest possible noise floor, and our USB Audio Class 2.0 output benefits from our latest jitter and noise reducing designs. A word clock input is included as well. This allows for an external word clock to be connected, pushing our reference-class SPDIF digital output performance even higher! And, a double-isolated Ethernet LAN port significantly reduces network / router noise, lowering the overall system noise floor for a clearer and more pristine audio signal.

However, improvements are not limited only to the N20’s exceptional audio performance. The new, bold 8.8” full-colour front panel display illustrates the album cover artwork as well as the album name and artist using a large and vibrant readout. And, practically speaking, an internal uninterrupted power supply (UPS) has the ability to perform safe shutdown under an abrupt power outage preventing system and/or disc corruption.

Ultra-High-Quality SPDIF and AES/EBU Digital Audio Outputs

The N20’s AES/EBU, BNC, Coaxial, and Optical outputs provide a superior musical presentation with some DACs due to the superior clock and oscillator. As opposed to asynchronous USB connections, where the DAC pulls packets of information from the player, N20’s SPDIF audio outputs push the signal out to the DAC at intervals defined by the on-board precision OCXO clock. With a clock this precise, once heard, you’ll want to use it.

Oven-Controlled Crystal Oscillator (OCXO) for Long-Term Jitter Reduction

OCXOs are among the most accurate and stable clocks in use today, and are orders of magnitude more accurate and stable than commonly used ordinary crystal oscillators usually found in computers. Temperature changes cause crystal oscillations to fluctuate, which can lead to jitter in the digital audio signal. Moreover, ordinary crystals are much less stable and lose accuracy over time. In OCXO clocks, a very stable, high-grade crystal oscillator is enclosed in a compartment and kept at a constant temperature to maintain an absolutely stable flow of information.

Precision DSD-to-PCM Conversion by FPGA

Many DACs support DSD decoding only on their USB inputs, but not on SPDIF. Additionally, some excellent DACs still in use are non-DSD compliant altogether. That’s why the Aurender N20 (and W20SE and N10) all feature this extremely high quality method of DSD-to-PCM conversion on-the-fly by FPGA. The resulting sampling frequency output is user selectable between 88.2kHz and 176.4kHz, gain is adjustable 1-6dB and a low-pass filter accommodates 24Hz, 30Hz, 40Hz and 50Hz settings.
