Inheriting Aurender's unique next-generation family design identity, the N30SA is visually distinguished by both its dual-chassis form factor and wide-screen full-color LCD display first seen on the A30 and N20. At first glance, you immediately notice its substantial presence, elegance, and grace – a visual metaphor of what to expect sonically. However, N30’s audiophile essence also lies within its inner beauty. N30SA takes its hardware and circuit topology innovations first explored on the N20 to its empirical conclusion. N30SA goes above and beyond the N20 in terms of noise and jitter reduction, increased dynamics, and uncompromised purity of the audio signal.
Physical Separation of Audio Circuitry and Power Supplies As mentioned, the N30SA consists of two separate chassis linked together by two cables. The power box houses all power supplies, display driver, HDD/SSD storage and all circuitry related to system control The audio box contains the display, SPDIF audio board with all digital output protocols, and the OCXO clock. Both chassis are distinguished by their 10mm thick top covers which act as an effective EMF shield as well as having anti-resonance properties. In the audiophile world, two-chassis designs connote “ultra-high-end” such as a separate CD transport / DAC or preamplifier with a separate power supply. However, in the N30SA, this is not just a mere stylistic gesture as significant benefits of fidelity are realized with this configuration. For example, the power box can be located up to 1.5m away from the audio box greatly reducing the potential for spurious noise pollution cause by physical interaction. But more importantly, the AC-powered linear power supply converts and delivers a clean DC power source from which the audio box is powered. This arrangement dramatically lowers the noise floor resulting in an uncannily quiet background from which music can emerge. Through segregation of the noise-inducing componentry such as the AC socket, LCD display driver, AC to DC power rectifier, hard drive spindle nose, and LAN port results in an unprecedented level of audio purity. Additional Noise Suppression Methods Employed In addition to removing AC power noise from the outside by converting it into a clean DC power, another major source of outside noise is from the ethernet cable. Like the AC/DC conversion, the N30SA’s LAN ports have similar behavior. LAN signals containing noise from the router are separated by galvanic isolation through a transformer and double-isolated LAN port and then transmitted to the audio box through a dedicated data cable. Viewing the audio outputs, located on the rear panel there is one each AES/EBU, BNC, Coax, Tos-Link, and Audio 2.0 USB. This audio signal processing unit outputs an extremely low noise audio signal made possible by a unique grounding technique, electrical isolation, and operation by DC power supplied from the power supply unit. The resulting noise floor is nearly unmeasurable.
OCXO Main Clock A high-quality Oven Controlled Crystal Oscillator (same as the one in W20SE) is used for the SPDIF outputs in the Aurender N30SA. Since only the parts directly related to audio playback are located together in one chassis, they can be totally isolated and free from noise generated from other than audio signal processing. That noise may occur inside the chassis and can be dealt with through meticulous internal processing. Word Clock Input This input allows interface with an external word or master clock which are offered by several high-performance DAC manufacturers. Simply put, a word clock is a device that is given the job of keeping perfect time and preventing digital audio data errors when multiple components are used together. Using the 75 Ω BNC connector as a connection method, both master clock and word clock inputs are supported for various scalability options.
