The external connectivity simply opens up options. I carry a camera bag most of the time so a Dap with an SSD attached (depending on the size of the SSD) is no big thing. If I had to fit it into a Tux pocket that would be a different thing,

 

 

Well at least no ones mentioned inertia charging optionswink.gif

 

All good ideas, as I said, but it isn't realistic. Sure, it is possible and probably would be very popular, but it isn't going to happen anytime soon. Also impedance matching is a joke with speakers. You have 4, 8, 16 ohm speakers. Not many different designs going on in the speaker world. Most of them use the same impedance (yes, there are exceptions), most consumer grade speakers are those configurations, thus making amping, preamping, etc. pretty easy and streamlined.

That's a bummer. I hope this is an issue they will address before the initial mass market release. Thanks for letting us know.

I hope its an issue they can address with a firmware update! frown.gif
Maybe reduce power consumption to increase the battery life and reduce heat at the same time..

Update:
James said its hardware, can't be fixed with firmware update frown.gif
I haven't tried long continuous run to see if it gets hot yet, time for a test run

I'll try tomorrow to see if it gets hot.

 

Many many devices get warm. Hot is an issue, warm isn't.

During battery charging or continuously playing the device for long hours?

Any chance to measure the temperature?

Didn't test long hours. But 20 mins makes it warm.
Not sure how to test a temperature on an object?

Have you ever touched the back cover of iPad 4 during operation?

Is it the X4 warmer than iPad 4?

Sorry never did that before. But it feels like when you are playing a game on your phone which is graphically demanding kind of warm. Not hot, but the warm kind.

Sorry I mean X3 (not X4 typo-error).


I can't imagine your "temp."but most probably it is still cooler than HM-901?

post #641 of 19485
So what's the estimated etr for the x5?
post #642 of 19485

total not need to worry about the warm of X3 because it is cooler than a Android phone, and take care not to listening X3 during charging.  

 

BTW, not sure whether it is suitable to compare to others in here but X3 will be more cool than some other DAPs, and the temperature also depend on what headphone, what sound track you are listening, don't forget that X3 can push out 500mW @ 16ohms headphones/earphones.

Thanks for the reassurance James. Now we can be more relieve and play the X3 without worries smily_headphones1.gif

I did not observe any heat issue with my X3... perhaps I mostly ampped it using LO...

So is the amp portion in X3 that produces the most heat?

This is a good idea to use X3 as the DAC/transport and then LO analog signal to external amp.
