Uses all audiophile grade components, including DALE resistors, WIMA
& EVOX caps (German brand), custom order NOVER (UK brand) caps, all
audiophile grade input & output sockets and gold IEC socket.
If you listen to this gear,
maybe you will be mistaken; it sounds just like a tube DAC , but it has
more dynamics and control, deep bass, thick mid and soft high, but you
can hear more detail.
1. Parallel D/A chips are
adopted in this design. By equipping each channel with two pieces of
top-grade parallel PCM1704U-K, the tone quality, dynamics and linearity
are all considerably improved.
2: Uses DIR9001 to take
the demodulation, the DIR9001 fixed Jitter value is as low as 50PS,
being the lowest Jitter demodulation chip at present, while
CS8414/CS8412 Jitter value is as high as 200PS. As a whole, this is not
good enough so that we carried out many modifications, like increase
the external connection phase locking circuit and so on, finally
successful in revising the electric circuit, using modified DIR9001
circuitry, to reduce the fixed jitter value to 20PS which is even lower
than any external phase locking circuit in top imported DACs costing
tens of thousands Chinese Yuan, whose Jitter values are above 40PS.
3. Power supply is
separated in different parts to match different electric circuitry. We
use 18 groups of newly designed parallel stabilized voltage supplies to
respectively power the different circuits, three transformers which
have a total power of 150W and a special filter capacitor which exceeds
40,000 UF. It is very obvious to tell from this design that a good
power supply is the foundation of an excellent sound quality and that I
believe every user will agree.
4. In this design,
the transformer, the digital and analog parts are all
compartment-shielded by aluminium sheets.
5: By using the
lowest time-base distortion CANARE BNC coaxial input terminal, we get
in practice a clearer sound with more sense of level than ordinary RCA
coaxial and fiber input.
6. To achieve the
best performance of this product, heavyweight pure aluminum alloy
machine box is used to prevent the eddy current of transformers from
interfering with the circuit board. The upper plate and bottom plate of
the box are both made from aluminum alloy which is as thick as 5MM, the
side plate 8MM and the face plate up to 12MM. The device net-weight is
12.5Kg without packing.
7: Benefits from the
high speed characteristic, excellent linearity and low phase distortion
of diamond differential circuit, which is being loved and supported by
more and more audio fans. Although the circuit is complex, the tone
quality is impressive. Weve done a lot of study and experiments on
diamond differential current these last two years, aiming to get a
better solution of circuit design.
For a DAC, high analyzing ability is the most
important requirement. The detailed recurrence of resolution lies in
the upward and downward characteristics and the noise level of the
output amplifier. Because output amplifier is the bottleneck, if the
upward characteristic is not good enough, the signal cannot be followed
correctly on time and the amplifier can only catch half or even less of
the signal level before it disappears. This leads to a downsizing of
the original range of signal output from DAC, which directly causes
obscurity or even loss of sound effect and a low analyzing ability. A
lot of DACs, therefore, even with a highly analytical D/A converter in
the digital section, cannot play most of the details due to its low
analog circuit speed. To get a good upward characteristic, the only way
is to use a high-speed low-noise transistor amplifier. Even operational
amplifier and tube cannot compare with high-speed low-noise transistor
amplifier in effectively lowering the TIM distortion which has a big
impact on the sound quality and promising a pure and pleasant sound
delivery.

Please note: If you want to listen by coaxial input most of the time, we
advise you to buy a professional coaxial cable for DAC3SE (DAC3SE has
no stock coaxial cable). You can buy our Canare coaxial cable with
DAC3SE together to save some shipping cost, or buy another brand
coaxial from another shop.
