About TEAC
TEAC Is a known and reputable name in the industry, creating a wide array of products that are accessible to the novice
music lover all the way to the professional or audiophile. Since 1953, TEAC was the first to create the 1/2-inch 4-track
cassette recorder, the 8-track reel-to-reel/mixer combo, the first R-DAT recorder, and the first MiniDisc digital multi-tracker
and CD scratcher. But they are not just pro audio. TEAC creates some of the cleanest and feature-packed units in the
audiophile and consumer audio market.
In a way, it makes sense that you want an audio company to have both hands in the proverbial cookie jar of pro and
consumer audio. With a grounding and product line of recording equipment, it seeks to complement consumer audio
gear, with the understanding of how effective recording is done which should ultimately translate into more efficient and
accurate high-end audio playback devices. Knowing how to record audio helps to understand not just how to play it back,
but to better recreate the original sound. TEAC knows this and it plays to their advantage.
About the NT-505
The NT-505 is a flagship dual monaural USB DAC with versatile network playback capabilities. It successfully incorporates
the latest network technologies, along with TEAC’s decades of accumulated audio design experience, in an attractive
package with an A4-sized footprint.
The NT-505 employs the latest VERITA AK4497 (developed by Asahi Kasei Microdevices) on each of the left and right
channels. It is a highly-regarded high-end audio DAC, and supports DSD512 (22.5MHz) and 768kHz/32-bit PCM formats,
achieving industry-leading ultra low distortion levels. OSRD (Over-sampling Ratio Doubler) technology, meanwhile,
significantly reduces out-of-band noise. As a result, the NT-505 has the refinement necessary to make the most of Hi-Res
formats, successfully processing information that lies outside the audible range.

The AK4497 is the flagship product of the Asahi Kasei Microdevices Audio4pro™ family, which has been developed for professional audio
equipment and high-end digital audio.
A dual monaural circuit configuration is used throughout, from the power supply (including power transformers), to the D/A
converters in the digital section and the Analog output stage. From the high-performance VERITA AK4497 D/A converters
to the massive toroidal-core power transformers, each element is configured for single channel processing. This prevents
mutual interference effects while reproducing a rich acoustic expressiveness. In addition, the Analog audio signals of both
the left and right channels are processed in full balanced mode soon after the D/A converters all the way to the output
terminal, contributing to an improved S/N ratio and extended dynamic range. This allows the fantastic sense of air that
Hi-Res formats possess to be processed and conveyed without any losses.
Connecting to your home network via a LAN cable, the NT-505 allows you to access Hi-Res music libraries on available
music servers and computers, as well as hundreds of millions of CD-quality tracks on Internet via music subscription
services like TIDAL and Qobuz, in addition to free music subscription service Spotify that delivers over 50 millions music
from the world. The NT-505 is also a Roon Ready product that enables Hi-Res audio streaming thanks to its high-perfor-
mance D/A converters.
