Hi,

I've had my DX100 for a year now. I've been using it with the Unique Melody Miracle.

I have a few issues.
 
1) The battery life doesn't even last 5 hours now. Screen off, blank drive (so no background processes). Any help?
 
2) Sometimes playback gets strange. A problem I couldn't solve easily was when there would be intermittent random pauses for a second or two a few times an hour. Any help here?
 

Version 1.37 firmware.

Thanks.

My DX100 arrived yesterday, a week and a day after I placed the order.  For years I've been listening to a Cowon J3 with PL50 IEMs. Recently I bought a pair of FitEar F111s which I thought paired very nicely with the J3. Wonderful sound, or so I thought until I plugged the F111s into the DX100.
 
I listen almost exclusively to classical music and the improvement with the DX100 over the J3 was quite noticeble. The most obvious was the bass extension and control.  This shows up in tracks that don't have deep bass ( i.e. Schubert's String Quintet) as stronger character, mainly in the lower registers.
 
But I was really shocked when I put on some CSN. The difference was dramatic, so much more well defined bass, greater attack in the guitar playing, and a pleasent filling out of the voices. It sounded like a different recording. There was so much going on that I had never heard before I was amazed. Not just little stuff like hearing them softly talk to each other but dramatic differences in the playing.
 
Needless to say I've very pleased. The DX100/F111 combo provides the same kind of engaging, enlivening listening I used to enjoy with my Stax CD94/CDA94 combo.  The downside is that now I have more recordings that are less enjoyable to listen to due to the poor quality of the recordings.  It's not surprising on the more compressed MP3s, but a flac of a nice performance of Beethoven's 4th Piano concerto sounded fairly lifeless compared to well-recorded pieces.
 
OTOH, I can't wait to hear what a good hi-res recording sounds like.
 
I did run into one very annoying glitch. There's a loud, sharp pop a few seconds after the DX100 is turned on.  It's shocking to the ear,  I have to remember to no put the IEMs in until after turning it on.  Is this a common occurence and can anything be done about it?

That, to me, is what a truly high end amplifier section can do.  The first place you notice it is in the bass.
 
That's why I simply can't understand why some people think they need to pair the DX100 with an external amp.  The amp section in the DX100 is absolutely stellar!
 
Oh well, to each his own I suppose...
 
Congrats on the new toy!

The pop is normal.  Most DX100 users have learned to plug in their IEM's after that pop from the amp.

As for the battery, I got this from the DX100 FAQ - http://www.head-fi.org/a/ibasso-dx100-faq
 
 
Getting the best from the battery
 
Keep wifi and bluetooth switched off unless you need them
 
Disable "Background data" option - this can be found in the "Accounts & sync settings" section from the Settings page'
 
you maybe want to root your DX100 and freeze suggested processes - also found in the FAQ  
also, try to calibrate your battery

One way to get rid of the pop is to use a delay switch, which would take more room, or a capacitor in the signal path to block the DC offset. The cap will add its own sound so they chose to leave it out and the relay also has contacts as well as requiring the room for it.

Beethoven's Piano Concerto No 4 is one of the recordings that just didn't cut it when played on the DX100/F111.  It's one of my favorite concertos and I was curious about hi-res sound so I bought a a 24/192 recording by Mackerras/Pizarro. Although I'm not enthralled with the performance (I fondly remember the Ivan Morevitz CD) the sound was just incredible. The textures and voices were so much clearer, lifelike, and with more detail than I've never heard before in a recording. 
 
Still curious, I bought the CD version on the 3rd movement for comparison. It sounds good but was like looking at a good reproduction of a Van Gogh painting instead of the real painting. Everything's a bit less well defined and vivid.
 
This poses a dilemma. Not all works have hi-res recordings, and even less for exceptional performances.  It's a hard choice between an exceptional performance and exceptional sound.
 
Then there's the problem of storage. The files are huge,  about 1.3 GB per concerto.  The movement I got is 10x larger on the 24/192 than CD qual.  I could fill up cards real fast. 
 
The design Micro SD slot is another weakness on DX100. The card isn't guided in cleanly like on other devices I've had and the card easily skews and jams. I don't relish swapping cards all the time.

Thanks for the info, hard to imagine that there's not a solution that preserves sound quality.
 
I've noticed when switching tracks there's a very short replay of the previous track (I think) and some little crackles and pops.  Somewhat annoying while listening, hopefully future firmware can clean up stuff like this.  However I'll live with it for the absolutely incredible sound the DX100 is capable of.

I just got my RSA 71b back from being updated. I am using the DX100 as a source and the combo, driving my balanced headphones is very fine. Very transparent and dynamic. Obviously, well maybe not, the bass quality is substantial and absolutely controlled. The DX100 makes an super source and of  course, not too shabby a all in one. :^) After an hour of both warming up, all I can say is, WOW!
