We at HIFIMAN noticed that someone (naming no names) had decided to take apart a newly purchased Jade II Amp. Aside from the question why would someone do such a thing we noticed that there were a number of discrepancies. We would hate to say lies, as we would like to think it was simply non intentional factual inaccuracy. We are now going to elaborate on a few of the points of contention so that the community has a more accurate frame of reference. A number of claims were made but we shall only look at 4 of them, if we were to go through everything this would become a very lengthy post. First, there is a comment regarding the IEC and its lack of safety, however its is an integral part of the design as its required to pass certification for bodies such as the FCC to enable it to be sold to the public. Second there was an assertion that the amp lacked grounding, along side a photo that showed the two grounding wires having been disconnected from the chassis. In the image below we show you just where those grounding connections are made. Third, we address the claim that the Jade II Amp is just a cheap copy of the STAX SRA-12S. Below we show the schematics of both amps and clarify the differences in their configuration and that the STAX unit uses a Single Ended MOSFET to the Jade II using a Differential OPAMP in the Pre-Amp stage. Likewise, the Power Amp out in the Jade is Transistor to MOSFET where the Stax uses MOSFET to Transistor in its output. Note that the capacitance is not the incorrectly stated 65pf but is actually 5.49pf. Lastly, we look at the headphone sockets. As can be seen below the Jade II uses a 1k Ohm resistor and it was claimed that a 5k would be better but functionally it makes little difference. Further you can also see that the Stax unit has no resistor whatsoever to offer any protection. The original poster appeared to us to have a bit of an axe to grind. Not only were the above and other inaccuracies but the post was filled with a lack of awareness. Multiple comments were directed more at China than HIFIMAN, at one point stating “Nothing from China is turned on here without being taken apart” It would seem that poster set out not to examine the inside of the Jade II Amp but to reinforce an already established opinion. Suggesting that Chinese means cheap and low-quality labour. However, the lowest paid, least educated HIFIMAN production worker costs at least US$15k per annum, a level approaching similar level workers in many western countries. This is HIFIMAN’s home-town, near the Tianjin Olympic Stadium. Tianjin is a typical, ordinary Chinese city compared to Beijing and Shanghai where the living costs are twice that of Tianjin.
