Totally agree, X5III is a much duller sounding DAP, I only meant it didn't have those sticking out trebles. NP5II is really impressive, with detailed, punchy, wide almost 3D sound. But, unfortunately, I just send it back to the seller. I could tolerate sharp trebles, but I couldn't stand those constant problems, and wasn't happy about those shaman dancing one had to perform in order to make the DAP do basic things without problems. I actually tried all those recovery wipes, and after that the DAP worked fine during the whole day (although I didn't activate Google and install 3-rd party apps this time), but again I had those tiny interruptions in the DAC mode (not actual pauses, although it does pauses in the DAC mode too, the DAP just skips a few milliseconds during playback). So I decided I don't wan't to deal with Cayin's negligence any more. Also don't really understand advocates for Cayin: give them a break, give them time. Every day we get shorter of breath and one day closer to death, so what time? They should have given proper testing to their device before starting sales. They released several updates already, and still those crucial bugs have not been fixed. Who knows, perhaps they can't be fixed at all. When one buys a TV and its screen turns off every 15 minute, and the support says "give us time we are working on the problem, and please report other bugs should you encounter any, yes we promised an update, but it won't be coming out as promised sorry", one just takes the TV back to where it was bought.
