i have some question regarding the dx50. i know it has been asked multiple times in this thread but i just want to clarify a few bit of information here since theres so many post saying te exact opposite information.. for that i really appreciate a reply(s)

first of all will there still be more frimware update, after the 1.2.8?

is USB DAC function will be/is possible to be implemeted in the future ?

what sound signature are the dx50? some says its neutral, while some say it s darkish and other says its bright by bit.

i have hifiman re0 and superlux hd669 which i'll be using with dx50 and both are slightluy bright. will dx50 sound too bright? im fine with my previous dap which is ipod touch gen 3 with cirus chip(some says cirus sounds bright), will dx50 sound brighter?

forgive my english. its not my mother language and no one here actually speak english

1.) After the 1.2.8: I have no idea but it is quite likely, I'm hoping they release an update that reduces how finicky the touch screen is.

 

2.)Usb dac: Again I have no idea but apparently they are releasing a driver for the DX90 and I was wondering as well if the DX50 would follow suit. I think they can but they may not so that people would buy their more expensive device kinda like how FIIO is not releasing a usb dac feature for the X1 but the X3 has it. This is mere speculation though, they may in the end release the a driver for the dx50.

 

3.)Sound signature: Personally I find it very close to neutral but on the warmer side of it. Taking my Modi/Vali stack as reference the dx50 is slightly less bright and it has a bit more body. I find the Modi/Vali stack quite neutral and transparent, in comparison the dx50 sounds a bit coloured. I like how it sounds with my neutral to bright headphones but I'm not a fan of how it sounds with my headphones that have a bit of body as the DX50 adds more body to this, eg: Akg403 and re400. It does have a sense of intimacy though with my Q701's over the Modi/Vali stack(my dx50 settings with the q701 =medium gain, vol-230). If this sound sig is an issue for you you can try eq'ing it a bit by dropping the 330 and 600Hz bands which should reduce the excess body and increasing the 1k-4k band brings the vocals and some higher pitched instruments a bit forward from the stock sig and I find this brings the dx50 closer to neutral imho. But you may like it as it is, stock.

 

I hope you find a bit of what I have said useful XD

 

Enjoy your dx50!!!!

I would like a feature just so you can name your playlists. I can't see it happening but it would be good as I have quite a few and it would be good to have an name to tell them apart.

Looks like the new FW will be out around May 15th according to ibasso. Can wait as I probably have the only one that still freezes, hopefully this will take care of it or it is going back.

Hi folks i just downsized from an AK120 to DX50 to save money and glad i did.   I found the single wolfson dac performs the same as the a k120 dual implementation.  If you give the DX50 WAVE files as opposed to FLAC it sounds a little better.  But the biggest improvement in sound is to upsample your wave CD rips to 192KHz 24-Bit.   It sounds amazing and close to the performance of the AK120 i had!  One other note from my experiments in up sampling the choice of upsample algorithm also makes a difference.  Some upsampler introduce distortions.  The best sound i've found is from iZoTope SRC Type II 24 Bit conversion and iZoTope SRC 44Khz --> 192 KHz conversion.   The Type II dithering sounds better then the mbit+ algorithm to my ears and my friends on his Arcam DAC.  The end result much more energy and PRAT to the sound,  and the little wolfson resolves way more from the recording.   I am guessing the 44Khz realtime upsample on chip must introduce a level of jitter on chip,  but pass it native 192Khz and it will blow you away.  Oh and i'm using the stock 1.2.8 with an AKG K550 headphone straight out of the headphone out with the gain turned up all the way!

If you are up to it, you can check out SOX, it's a better converter than the iZoTope and better value(free).

What is the fastest and also reliable mini card to use with this DAP? Does speed matter as much as reliability?

Thank you.
post #12757 of 14412

Any card works fine.  I had to get a SanDisk 64 Pixtor, all they had at BestBuy and I didn't want to wait and get a cheaper one through Amazon for $12 less.  Get a decent card, but you really don't need the fastest bestest one.  Unless you feel you WANT the fastest bestest one.  :normal_smile :

No, I am a cheap, old dog. Only like "bestest" in bed.

I experimented with SoX before sample manager on my mac. Even in the best settings SoX had not bad sound quality but no where as good as iZoTope. Sample manager was pretty cheap to.

I've had good experiences with both the Transcend 64GB MicroSDXC Class10 UHS-1 (what I use in the DX50 currently) and the SanDisk Ultra 64 GB microSDXC Class 10 UHS-1, with the Transcend having a bit faster read/write speeds on average.  The speed differences are more noticeable when you're managing files then when you're accessing the cards in the DAP.  Both are currently on Amazon for under $40, but if you need less storage, the 32GB versions are $20 each.  Price to performance ratio is excellent!

You are upsampling red book 16/44 to 24/192?

that is just a waste of memory, it can't sound better, it can easily sound worse.

Not all the time. If you are playing a file thru a USB source, upsampling can help counteract the effects of Jitter. But I'd rather do a real-time up-sampling than storing the up-sampled files. I agree, it's a waste of storage space.

Does anybody had use the USB vith an external dac? could it work?

It will not work.

It is very useful and I really appreciate it! :D

 

btw I've been listening my Superlux HD669 through my DX50 for hours! I must say what are you saying are true.

at first glance of hearing(does "glance" work for "hearing"?) it sounds a little bit bright as I'm used to dark-sounding iPod touch gen3->fiio L6->Fiio E11 with bass boost 1. The Fiio E11 tamed my iPod's treble and I perceived the mid-bass boost as well as the recessed high as warm, full bodied sounding. However I was wrong.

Upon listening for hours I found that DX50's low bass are actually good on 1.2.8 firmware! mid is somewhat not recessed like the iPod touch + fiio combo and I have no trouble picking electric guitar from playing my messy, muffled MP3 J-pop songs(instrument overlapping all over the place). I also experience the same kind of body thickness sound like you said, the body is really something that thin sounding cans really fit! now my HD669 sounds much more balanced. I was wrong perceiving that every DAP that reproduce the high really well will always be bright sounding.

 

What I feel lacking from the DX50 is only the vocal, as it feels a little bit laidback, and the sweet female vocal from the E11. Maybe I'm just not used to it yet.

The instrument seperation, detail as well as the soundstage from this little thing is just ridiculous. my iPod and Fiio combo won't be able to sound anywhere as detailed as this thing. I can't imagine how studio V sounds like after listening to this DAP D:

I can confirm this thing sounds warm and good for thin-sounding cans.

 

you drive your Q701 with medium gain setting? that's weird.. because I'm driving my HD669 on high gain because the dynamics are much better, instrument separation, detail and soundstage are much better on this setting too! they sound a little bit over-sibiliant to my ear on high gain though

 

 

I'm loving this DAP to death, the only problems are most of my mp3 song sound less dynamic and refined compared to my loseless songs, the touchscreen are a little bit sensitive to scroll and now I can tell that I have some fake downloaded flacs..
