the lather case only in blue ?!
no, you can get it in brown as well

the lather case only in blue ?!
Hi
It is a very natural sounding dap
Not clinical like the Ak j
The good -battery life ,menue response ,size, eq ,drives 32 ohm headphons ok
The bad - no line out /on digital out , the lather case only in blue ?!
Just surpassed 80 hours on MP3 playback.
Speaking as someone who designs analog/digital audio gear (not daps).
Burn-in, unless we're talking about something physical like a speaker cone, or something inconsistent like vacuum tubes, is all in our heads. Modern daps use precision components and have for years. Even the lower end ones. Our brains have a tendency to fool us, everyone is susceptible. Especially if your brain is subconsciously 'looking' for a difference. If we expect there to be a difference after ten hours, we'll often think we hear it. If we have doubts about a product, we might not.
Simply put, if a modern piece of electronics gear has no moving parts, and is using modern components, brand-name capacitors and codecs/dacs, then you should expect NO change in characteristics that are actually there, at least during the first few years. If a modern piece of gear with no moving parts changes its audio characteristics within hours/days of being brand-new, then it's either defective, or poorly designed, or as a stretch it has been built-in to trick the consumer.
For my analog/digital work, I have to pour over datasheets for all kinds of components. Including codecs, adcs, dacs and opamps (amps). Audio/electrical charactaristics change with temperature, current, depending on how you use it, and so on. But burn-in time isn't a factor. It's not the 1970s anymore.
The way these things are designed, saying there's burn-in time for the microcontroller coupled with the codec/dac, precision output caps and/or possible a headphone amp, makes about as much sense as needing to burn-in a glass by filling it with water several times, before it can be full. At least to EEs who work with modern parts.
~86 hours from full to dead on MP3 playback unloaded. I'll do one more test on AAC files loaded and extrapolate the difference.

This are the things I am wondering about, maybe someone knows the answers:
About the burn in time: It might be the case that the burn in time is not so much the DAP but instead our brains. When listening to sounds you never heard before your ears/brains must learn to distinguish from other sounds it heard in the past. Like learning a new language. At first you are not able to hear all kind of subtle differences, but over time you learn to distinguish and recognize the differences.
The earphones are a big part of the experience and need to be able to (re)produce the nuances we (think to) hear. Maybe the earphones we use are simply not good enough to showcase the quality of the DAP.
Another thing I am wondering is if the quality of the music is good enough to demonstrate the (perceived) better quality. I mean when I am listening to flacs I created from CD's, are those good enough to show the differences in quality between the better players.
The DA conversion always introduces some noise(/distortion?) to the sound (compared to the original sound). Is it possible that the better quality DAP's make it possible to hear this noise, while for a less quality DAP this noise never reaches the output?
So I am currently using RHA MA750 earphones. Are these good enough for the D? Or should I invest more money in the earphones?
Thanks everyone for all the interesting points they make in this thread. I am going slowly through all of it and enjoy it tremendously.

Yes, the RHA MA-750's are fantastic with the Plenue D.. I personally prefer a Bassier Sound signature, so I prefer the MA-600's while on the go, and the T10's when wanting to have more refinement. But like I said, I prefer a darker signature.. If you want a more neutral tone.. The 750's are the way to go.
