Well, it may surprise many of you because I am a special case, so to speak, a music fan playing and living with music rather then taking care of a family and children, so I may be the only one playing music with Zidoo Neo S so much time ... actually I just wish to hear music no matter I doing work, job, eat or sleep ... I just wanted something, some player which can do that and Zidoo can do that but in certain conditions. First let me explain what I found after 3 hours of uninterrupted play: high temperature on a nano-transistor (and also on the digital power supply). In order to find out this information I had to do all the combinations of possible tests (with the top aluminium lid on), namely: activated and disabled save-screen, activated or disabled the VU-meters, remove and plugin the internet cable during the audition ... and absolutely nothing gave results except one thing: I set aside the upper aluminium lid. Once I did this, the device can play 12-24 hours or even non-stop. From here it can only result in one conclusion: something on the motherboard is still heating. The processor does not, because it has a good radiator, ... other integrated circuits no, because there is no hot air from them, but, there is a set of nano-transistors that are in series with the audio signal and have the role to interrupt/switch at the command of the switch from Dac to HDMI (also supplemented with a micro-mechanical switch with gold contacts that are heard doing click click). Nobody knows what those nano-transistor are and will never find them And because they are so small the hot air flow cannot detected or measured with the IR thermometer, because the IR rase is thicker than the nanotransistor and gives errors. Given the results, my only possibility is to listen to music without the top cover aluminum lid. If I do not do this, then not only the interruptions will appear, but there is the risk that those nano-transistors, invisible with the naked eyes, may irreversible change parameters and permanently interrupt the signal and then that would mean the failure of the motherboard. Only some laser IR thermometers, through extremely careful measurements of the heated air nanovolumes, can offer some clues. But still it will be useless, because the nanotransistors cannot be seen with the naked eye, besides the fact that they are directly embedded on the wiring ... so those can not be replaced but the entire motherboard. However, considering that it goes absolutely without any interruption for over 12 hours, for me as a user I am super-satisfied. Sometime next year I will be able to build another lid, through laser technology, at perfectly identical dimensions, and then make a set of parallel slots to eliminate hot air. I will make a technical drawing, an execution project and I will buy an iron sheet of the same thickness. About 3 hours goes well and with the original aluminium lid, so users who are not fans like me, and who would not listen more than 2 hours without break, would never get to notice these problems. I, ... I could say, ... I am a unique case, but at the same time my expertise could be useful to both users and producers. So the conclusion is that except for the heat problem, Zidoo Neo S is working excellent and if using without the top lid cover, then it plays 24 hours continuously without any problems.
