GENERAL INTRODUCTION
One DAC + one Music one Volume number with the
most advanced features. Always decode DSD with: DSD x 1 to
DSD x 8 with all different sampling inputs. STAR Pure DSD
DAC optimizes digital music sources to bring the very natural
sound quality, closest to the sound of vinyl records. STAR Dac
brings convenience and savings to audio players as well as a
markedly improved hi-end sound system.
Quang Hao products are designed in Italy and tested in
Denmark, made in Vietnam.
Please read this User's Guide before installing and operating
your device to make the most of its features.
DSD proved to be completely superior to PCM and
compressed music formats both in terms of parameters and
theoretical advantages. In addition, the DSD has a very high
sampling frequency, so it is only necessary to use simple filters
at low frequency during signal processing and decoding,
similar to the filters in the speaker crossover. . Reducing the
level of filtering will cause less difference in sound from the
original. Only filtering the signal at a low frequency also helps
the decoding process to achieve very high accuracy, less
noise, noise and distortion, thereby producing sound with
high, near-noise cleanliness like there's no background noise,
the same static background.
In our audio performance tests, we are always looking to be
sure of an objective result using many different people,
systems, and ears. This means that the results here are not
personal to me, to Andrea or Pavel Pogodin, and it is not as
subjective as many other trials published online.
All tests done proved the validity of this adapter, it was much
better than the Saber ES9018. The details are at the highest
level, there is no fatigue while listening and the spatial
reproduction is excellent.
In this design, we use CT7302 chip to receive input signals
such as; Optical ports, spdf, aes, I2S, I2s-USB are diverse
input options, with I2S output always on DSDx8- or DSD 512,
and behind is FIF filter with R2R resistors (alternative) DAC
chips), so the natural sound that most DAC chips do not have,
excludes some classic chips like AD1865, PCM63,
TDAC1541. This is a product combining classic and modern
design, Quang Hao-Pavel Pogodin- Andrea hopes to bring
you the most comfortable relaxing moments and enjoying the
highest sound with the lowest investment cost. !!!
DAC incorporates Rasberry Pi4 to become a dedicated
Music Server. Take advantage of endless digital music
sources, especially DSD64,128, 256 formats that are very
close to SA-CD sound. It is clear that time for using
expensive CD packages and SA-CD is over.
This Music Server will let you choose the highest resolution
audio files. Actually, DAC decodes all formats of digital
music files up to DSD 512, and plays the best DSD 256.
