Gustard DAC A20H - Dual AK4497 (New Flagship model)


GUSTARD recently announced a new DAC-- A20H, It is the successor of X20 DAC, Gustard have researched DAC for years and developed some good products in very good reputation. A20H is based on dual AK4497 DAC chips which is the latest flagship product from AKM, The DAC is specially optimized for better performance and sound presentation. LPF section is constructed with discrete components at class A working status,It is the biggest advantage than the other DACs on market,The transistors in LPF are matched for original sound.
GUSTARD A20H premium dual AK4497 DSD DAC D/A converter with XMOS asynchronous USB, Original fully balanced circuit from DA to amplifier without any conversion,With unbalanced output and balanced output,Integrated high performance headphone amplifier
Selling at: $1300 $1200 (Pre-order offered)
-------------------------------------- (Note: the DACs/U12 default does not come with any standard USB cable)
Gustard DAC-X20 - Dual ES9018 Sabre - Flagship model


- Dual ESS Technology Sabre Reference 32bit ES9018 DAC chip,R and L sound Chanel one on each side - Automatic adaptation master clock technology and Asynchronous master clock technology Two clock mode can be freely selected. - XMOS 32bit USB receiver chip which is best performance asynchronous USB audio solution. - CPLD programmable logic device. Soft control ES9018. - Three files gain, volume can be adjusted. Attenuation adjustable from 0 to -99DB. - TFT LCD screen, adjustable contrast. - Power supply with two O-type transformers, Digital and Analog independent power supply, and use Discrete Components regulation Voltage stabilization. - Full balance Discrete components Analog Line. Balance / RCA output simultaneously. - Digital Input: balanced Spdif AES/EBU port, RCA, Toslink Optical input and USB,(Key switch) - Come with Remote controller
Selling at X20u: $1250 $1150 X20 bundle pack: X20 + U12 + HD230 0.5m HDMI cable : $1420 $1300. Feedback and review going through U12 before go to the X20 proven a much better performance setup and support DSD 512 as well. Even Gustard has confirm this. With a little bit more investment, you get a better performance.
(Cheapest in the market. Rather i say it perform better than other more high end DSD Sabre DAC in the market, put it this way is that the price you are paying for such quality and performance, is something you should consider.)

ustard H10 High End Class A Headphone Amplifier


Class A headphone amplifier with high current current output. For each channel in the amp it has 2 independent amplification circuit. The H10 features two independent amplification circuits for the left and right channels, four gain switches, two RCA inputs, and two balanced XLR inputs. There are 4 pre-buffer adjustment functions build in with the amplfier and that mean the amplifier using pre-stage buffer and main amplifier components. By using 4 paris audio power tube output circuit, the H10 could easily drive variety of different impedance headphones. The Gustard H10 built in with 2pcs 25W transformer and they correspond left and right channels power supply and highly reduce the channel crosstalk. Selling at: a) $525

b>Gustard XMOS U12 USB Interface

USB Interfaces not only provide just the various interface for connection to DAC, it is also a high Performance device to reduce the jitter to the minimum. It is often encourage to go through them before to a DAC. Not even a Asyn DAC can reduce much jitter as much as an USB Interface does
- DSD support 128, PCM supports 384K - wo 0.1PPM precision crystal 45.1584M 49.1520M - International voltage AC115V-230V, the need to manually adjust - XMOS-U8 chip, support 32BIT/500MIPS digital signal processing unit - Input :USB input x1 - A total of four kinds of output: Coaxial (RCA), optical fiber, AES / EBU, IIS (HDMI port) Coaxial fiber AES / EBU output formats IEC60958 and AES3-r2009 standard limits the maximum support 24Bit / 192kHz; IIS can transmit 32B 384K
Selling at: $225

Available in Black
------------------------------------------------ Xiang Sheng DA-05A - Dual PCM1794 (This is not a Tube DAC)


- Using the famous TE8802L as USB chip (TE8802L is a upgrade version from TE7022) which can support 24bit/192K. It is an Asynchronous - USB part adopts IIS output signal from TE8802L, through PCM1794A decoding, not TE8802Ls Spdif signal, because the Spdif signal should though CS8416 chip, then enter PCM1794A , thus will increase the jitter value, lose the advantage of asynchronous, also cannot play out the advantage of TE8802L. - PCM1794 as decoding part,and with the TI's Mono mode, can provide more dynamic and wider frequency response. - Using 9 OPA2604 for op-amps which made by Korea,and with gold coated RCA connectors and coaxial connector. - 5 digital signal input switching : AES balance output ,BNC, coaxial , fiber optic , USB - 2 Output Level :balance output: 9V unbalance output:2V - LED display on the sampling rate - ALL resistors and capacitors are audiophile grade
Selling at: a) $455 $399 (Promotion) Available in Black / Silver
