To our valued customers. We feel there is clarification needed for the change made to the DX160, which we are referring to as the 2020 version now. The only reason any change was made initially was because the screen we were using, the Sharp screen, is we can no longer obtain this screen. To replace this we have purchased the JDI screen. While the resolution is the same, the quality is slightly lower. This isn't noticeable until comparing side by side but it does not have quite the color impact. To compensate for this we then looked to see if there was any way we could improve the DX160. For this we ran many tests on components. We found one op amp that does improve the dynamics and this is buffer is what we have used. The change to The change to CTIA for monitors with an inline mic, is something we had been asked about many times and we decided to implement this at this time. We have never and will never use customers as beta testers unless we make this known as we have done with a few past firmware beta versions. We value all of you and have always valued your opinion and desire for enjoyable sound and a meaningful musical experience. If there are any owners of the DX160 2019 that wish to have their dap updated to the latest buffer we will offer this service for 32 USD. We are charging 10 USD for the buffers, free labor and 22 USD expedited shipping back to you. For Hong Kong, due to the close proximity, the cost is 10 USD for the buffers and 5 USD for the shipping.
