As I told you for me the the Fiio products are history. I will not touch another one no matter how many stellar reviews they will receive. At least I've learned a valuable lesson. In the end is very simple if they don't care about me why I need to care about them.
For the sake of fairness I need to make a clarifications:
The wheel was broken just several weeks before warranty but I didn't knew as I was in holiday. The claim was done shortly after my return and was already out of warranty. As I couldn't prove that was happens in the warranty period I didn't contest their decision to charged and I've paid. I was just willing to say that a serious company was at least quietly accepting an extended warranty only for this wheel that I think that is wrongly designed and wrongly implemented. For the firmware part I must say that many modern devices used in Hifi are now software dependent (players, DACS, streamers etc). As I said I don't know any product that has software involved that will not require further fixing, tuning or just pure improvements. A company , especially providing devices supposed to be HIFi class, that is not striving to obtain the maximum that could be obtained from a device released to the market and advertised as High class audio device is does not worth my money and attention.
I'm not willing to finance yearly release of not final engineered products just for the sake of releasing.
In this idea why the gen 2 was necessary? Why even shortly after X7 was released? If for X7 it could be argued that is actually different device for X5 gen II is not the case. Instead they could split their efforts and many to maximize X5 at his full potential and to make the new X7 better that they did with x5. Otherwise they will continuously release incomplete developed and supported products.
Also think about the K5 docking station. It doesn't support X5 gen 1. The X5 gen I was released internationally ~ 2years ago and now they considered already obsolete. Taking into account that a new product need some serious time from the idea to the final implementation it seems that they don't have any strategy even for short term.
As I said is only one target: The customer wallet.
For all the Fiio owners I wish only the best of luck and enjoy your device.
