In all honesty, as DACs, the difference in sound between even an iPhone and most DAPs is relatively small. The headphone amps, well, YMMV depending on the headphones or IEMs used, but assuming a low output impedance and enough drive, they all are fairly decent.  I had a couple of situations where I was using the DX100 as a digital source and the resulting output, through another DAC was horrid-sounding. When I tried it with a known good DAC, I came to the conclusion that somehow the unit was distorting the digital output, as a reboot fixed the problem. As well, I felt the sound quality using ALAC files was worse than when using FLAC, which I hadn't expected. Knowing as we do that the software for these DAPs is quite poor in many ways, we can't really be sure what FatmanSize48 isn't hearing is a problem with the software.

So, honestly, I think what amounts to putting someone down because their bad experience, which could VERY well be the result of the poor software, is unreasonable.
Hey Currawong, I didn't see either my nor the other quoted posts as putting anyone down. I think we've been misunderstood. FatmanSize48 told us his situation, and asked "what to do?" I'm pretty sure from earlier posts he'd tried all the usual resets and updates but still thought his DAP was faulty which is why he returned it with an RMA. I simply suggested asking for a refund because I think iBasso returning his DAP to him or even sending a replacement seeing as they said his was not faulty would still result in his disappointment. And that is what he subsequently did. I did add that I did not find mine sounded as he described. The forum is full of differing views on the SQ of everything. Nothing new nor a putdown.

And tak made a totally reasonable comment. I actually agree with him, because from my experience with iBasso, they seem truly conscious of good customer service and have offered refunds and exchanges quite often to customers from what I've read on this forum.

Because I'm sure it's a misunderstanding, I've not meant or taken any offence but did feel the need to reply to put the record straight at least from my point of view.

Are we all cool?

Not a reset button but a reset procedure. Like Tin427 says, if the unit locks up press and hold the power and volume up button and keep holding after the unit shuts down until it restarts with the usual start screen. Release then. At boot up you will see a recovery screen. Try reboot first however this rarely works alone. Use the volume up and down buttons to scroll down to factory reset and wipe. MAKE SURE YOU REMOVE YOUR SD CARD TO AVOID REFORMATTING IT
After restarting which it should do, your DX will be set to factory defaults. Insert your SD card and scan. Should be all good after that.

I think Soren has put this in the FAQ in the Wiki section, but it does keep coming up here. If you have any other problems, check out Soren's FAQ first or the bugs thread which has a lot of issues covered there too.

EDIT: Seems it is not necessary to remove SD during reset. Thanks Musicheaven.

Hi happy DX50 owners,

 

I'm new here, and I went over the whole thread (four days!). I'd like to share my two cents with you guys.

 

After playing with this little thing for several weeks, I have a feeling that the internal amp of the DX50 may not be that bad. It might be its DAC volume control that lowers down the resolution and dynamic range of the headphone out. I started to think about this when I pluged a pair of cheap Ety kids' (300 Ohms) into it, cranked the volume all the way up at low gain and found it sounded really good with a lot of details and good dynamics.

 

I normally listen at volume about 200 with my diy ciem. I tried to amp the LO with O2 at the same volume and did an AB test (kind of) by quickly swithing the IEM between DX50's HO and O2's and I could hear little difference (the bass could be a little better on O2 if I have to say). However, if I set volume at 255 while lower down O2's, it sounded much better to my ears (I can't AB them in this case though, so it could be just my imagination...).

 

I then used this DAP as an amp: just start it up without playing anything, and use its line out as a line in, it does work as an AMP only (CAUTION: try this at your own risk!!! It may damage the DAP and/or your ears). In this setup I AB'ed DX50 and O2; I could feel some difference but failed to tell them when blind.

 

Could anyone running it with an good amp please help me confirm this? Just set DX's volume at 200 or even lower and turn up the amp's; see if you loose any SQ. I suspect that a lower volume  sacrifices dynamic range too much. If this is the case, I wonder if we can further lower the lowest gain so that the DAC can work at its full power. Two surface mount resistors may need to be changed and I don't think I can do this by myself...

 

The DX50 sounds good enough to me for portable use. At my desk, I also use it with a pair of Hafler TRM 8.1 monitors sometimes and the DX's LO volume control really helps!

 

BTW: I prefer the sound of 1.2.2 over 1.2.3beta. Simply better clarity.

 

I also paired DX50 with O2. The LO volume has different effect depending on which IEM you use. With JH16 I need to set the volume in DX50 to 200. If I go higher the lows are just painfully too much and the volume pot in O2 can only travel as far as the 8 o'clock position . But with my H-200 the sweet spot is 245. My H-200 really shines with O2. It retrieves details with astonishing clarity. 

 

JDS Labs recommends setting the LO volume of any O2 source at 60 - 80%. I think JH16 complies with this recommendation :)

I took out the battery, and still froze.

Did anyone had same problem or similar?

Thanks

Couple of things, your problem was described earlier with a solution so back track and search through this thread and you shall find the answer. Secondly did you also check the FAQ section with the link given on the first page?

Edit: I take it back sounds like you already tried the solution. One more thing. It happened to me and I had to try resetting many times, something like 3 or 4 consecutive times and eventually it went into recovery mode, then factory reset by wiping the internal memory. After that it was good to go.

Just to clarify, I always left my SD card in the dap and did many factory resets from the recovery screen. It never deleted anything from my microSD card. The only thing it did is erase the internal memory.

Hi, I'm going to get DX50 and would like to use it with my JH-3A. Can anyone tell me, on conector on DX50 side, it's TS connector and signal is on tip, right?

I've read and heard some very good things about the Momentum......so I've taken the plunge and bought an excellent pair of second hand "Over the Ear" Momentums to try with the DX50 and O2/ODAC combos. Should be with me on Tuesday :D:D 

 

I'm also hoping that they should sound good straight out of my iPhone 5 and iPad 4 for spotify (just need to get a HRT Microstreamer for the iDevices and should be sorted) :D

I did it with both and started to think I bought a DX50 and yet the iPad and iPhone sounded amazing, then after the shock I told myself yeah but... Fill in the blanks biggrin.gif

Great headphones I'd be surprised you'd have anything negative to say about them. You'll love the switchable cable for total remote iPhone control. smily_headphones1.gif

Thanks Jon. Must admit I have never left mine in after seeing a "reformatting SD card" message at some point early on, and took precautions.

No worries, like you I was initially uncomfortable leaving the card in but then I told myself what the heck I have a backup.

You should really test it for yourself (and share your impressions if you wish) - the opinions on this thread are widely apart... I for example am quite happy with the combination (but am just new to headfi stuff).

 

By the way: I quickly tried plugging my dx50 to my home hifi (marantz sr7007 and b&w 804 nautilus), very disappointing, it just sounded sort of distorted and flat and just ugly (sorry I don't have the vocabulary to describe the sound better). (I'll have to try plugging it differently and with a difft cable because I can't believe it's so bad... and to compare properly with playing the same FLAC files directly on the internal DAC of the Marantz.)
