From Xindak website:

------The electric circuit and function The key elements of DAC-5 is AD1852 from AD company, and its converting precision is 24bit/192kHz.The electronic circuit principle is upgrading the digital data signal from CD disc to 24bit/96kHz or 24bit/192kHz at first, then processing D/A convert through ADl852. 
-------The analog filter circuit adopts the low-noise non-inductive resistor and the operational amplifier IC 0PA2604 from BB company. The analog output is divided into tube output and operational amplifier output, the former one is RCA single-ended output, and the latter is balanced output. The basic structure of electronic circuit is classical, it can up-sampling the digital signal recorded in common CD player and PCM format to achieve higher D/A converting precision and highly improve the sound performance on dynamics, frequency extension and solution. 
--------The DAC-5 also has its own characteristics on processing of the electronic circuit, such as ¡°adopting the patent technology of avoiding dynamic invalidation of capacitors¡±. In the introduction, it is said that technology could decrease the distortion of the high frequency and improve the sound performance. Though there is no more detailed introduction on that, but one point is confirmed that capacitors could influence the sound of Hi-Fi products, no matter under dynamic invalidation or static invalidation. 
---------Two separate transformers supply the power to different channel. This DAC-5 adopts two separate toroidal transformers for right and left channel separately. In addition, there are 6 groups independent positive voltage regulators for power supply and there are 5 piece of high precision integrating regulator IC in total. That could assure the purity and steady of the power supply, which is also useful for block and converting electronic circuit, in order to further ensure the good quality of sound. 
----------The tube output adopts E88CC(6922EH), and the balance output adopts operational amplifier IC OPAl34PA. 
----------Aluminum front and steel cabinet are common but with excellent handcraft. Besides a bigger power  It makes the whole device very exquisite of the little press-button and indicator light. The arranging order is select button of signal input channel, coaxial signal input indicator, fiber input indicator, digital signal lock indicator (the indicator light turns on when receiving stable digital signal), 96kHz indicator (the indicator light turning on when the device is setting as the 24bit/96Hz mode), 192 kHz indicator (the indicator light turning on when the device is setting as the 24bit/192Hz mode), mode select press-button. 
-----------SPDIF coaxial input, two groups of RCA output connecters (one for tube, and the other for transistor), one group of balance output connecters. 
-----------The power cord is plugtype, which is convenient for the customer to change different power cord if need. The internal handcraft of Xindak amplifier is famous for its excellence, as well as for DAC-5.  Among all the elements, the capacitors, resistors and operational amplifiers are famous brand products, and even the connection cable is chosen.
