At such a premium I still can't figure out why hifiman released such a product with hiss. The hiss isn't only an issue with that format but using a standard unit with sensitive IEMs or headphones induces a lot of hiss. For something that is suppose to be marketed to the portable sector, that is completely unacceptable. What do most people use on the go? They use IEMs or portable headphones lol.

This is the translation of Garyvictor's review of the DX100 (Part one of Two):
 
"I can still remember it was around 2010, Mini Audio (Ibasso)'s chief audio designer, Old Fellow (as he is known by that nick name in China) told me, he wanted to develop a new and unique kind of portable DAP.  During the Christmas of 2011, Mini Audio's first portable DAP, the DX100, (also known as Hibino's HDP-R10) finally somewhat appeared within our glimpse.  It is interesting to talk about the developmental milestone of this unique DAP, I believe within the forum (erji), headfiers still remember that groundbreaking iRiver hard drive player iHP120? Yes, it is that common looking player with a 20g hard drive player.  At that time that was the only portable player that came with an optical out.  It is this player that planted the seed of thinking about having a portable but completely separate system.  That is transport+DAC+amp.  Also at the time, because of this player (iHP120), Old Fellow developed the MAD-D10, a DAC/Amp combo, which I considered a groundbreaking classic.  Subsequently, the portable amplifiers that Mini Audio developed flourished within the wall of our country but its fragrance spreads outside the wall.  These were well received with very good sales records overseas; of which, the D4 was particularly successful.  Inside China, the earlier model that left its mark had to be the MAD05.  Later, during RSA (Ray Samuels)'s advance portable amp's reigning period, the unusual rise of the P3-DIY allowed the headfiers in China to come to know the Mini Audio brand.
 
Mini Audio's chief audio designer, Old Fellow, is a very experienced hifi system designer and a very low key but very meticulous person.  He played very good guitar when he was young and had a handsome look, that at 40 something years old was recognized by AF2000 as only 30 something.  Since the early 1990s, Old Fellow has participated in many audio design and developed solutions to many audio problems.  In 2006, he created Mini Audio and the world's first double lithium battery DAC (MAD-01).  As time goes by, several years have passed, and Mini Audio has not stopped progressing.  Their product lines were well received internationally including from the D4 that used a 9V battery to the D6 with lithium battery.  From the pioneering P3-DIY to the improved P4, and the later PB2/DB2 combo, set the standard for portable balance audio.  The PB2/DB2 combo has received both domestic and international headfier's consensus as achieving highly regarded audio accomplishment.  Therefore, from digital conversion to amplification and back to digital conversion, and from single unit to separate unit back to single unit, Mini Audio accumulated abundant experience in the development of initial sound processing to amplification.  In 2010, Mini Audio started to work in cooperation with the famous Japanese company Hibino. And after much work and development finally giving us the DX100, or the Japanese version of HDP-R10.  According to the rumor, the Japanese company has put together TV commercials and is going to heavily advertise this unique music player.
 
A word about this Hibino company. Hibino's major business focuses on audio and video equipment--LED monitors, etc. and is the main sponsor of the famous Japanese Red White singing competition (may be equivalent to American Idol)?  It is an authorized dealer of many high-end hifi brands.  However, in terms of audio hifi development, Mini Audio (Ibasso) is the only Chinese partner.  
 
Back to the DX100, what makes me surprised is the high -116 db S/N ratio, this almost represents absence of noise.  With the C4's -108db, I am not able to hear any background noise.  So we know how special it is with -116.  Under 20Khz the separation of sound can also achieve an admirable 82db.  These specs are the highest of what I have seen in a DAP." 
 
I'll will continue in a bit of his audition.

I am very interested in the DX100 as a source using the coax out to feed my JH3a.
Comments about the coax out from early users would be great.

Because of the lengthy review, I'll be brief and only highlight the part I thought people will like to hear.
 
"Testing-Part I:
 
DX100 uses Android os version 2.3.1, internal version is 2.6.32.27....basic operation is smooth, opening web pages and changing sound tracks did not result in any hesitation.  DX100 has its own music player, as such, using the Android's own volume control while playing music has no effect.  Inside the Ibasso dedicated music player, one can upsampling or downsampling or choose specific sampling rate.  One thing needs to remind everyone which is this particular version of os, according to Old Fellow, has unique or dedicated linkage or shakhand with the dedicated music player, so if anyone attempts to upgrade or downgrade from this version of OS may result in operation difficulty of the entire system.  DX100's 6.3 and 3.5 headphone out has the same output.  However, volume control is a little different.  Volume control from 0 to 140 steps is finer, whereas between steps 140-220, the steps are equal, and from 220-255, the individual steps have more volume increase.  Battery life was fully charged at 4:30 PM and has been in use until now which is 1:30 am with one bar remaining.  I expect may be it can run for another hour.
 
Testing-Part II:
 
Turn on and turn off, and when volume is at max 255, there is some noise that can be heard clearly.  ES3 normal volume setting is 155.  When music is playing the screen will automatically turn off without any noice.
 
Floor noise or background noise:  under low volume and not playing music condition, there is absent of any noise throughout the sound spectrum.  At mid volume level and thoughout the sound spectrum, you barely can hear any noise.  At high volume you can very slightly hear some noise.  Due to the sensitivity of the ES3 at 126db, 16ohm, normally only low level of volume is needed and at this level there is no background noise noted.
 
Noise in changing track, and or during pausing:  when changing sound tracks or pausing, there is a very slight "ka ta" sound.  Starting Wifi while music is playing will have some sligh noise.  Surfing web pages while playing music produces no noise.  When playing music and surfing web pages, changing web pages and turning on and off the screen produces no noise at all.  Later, changing to ED 10, C5, and D500 the lower sensitive phones did not produce any noise.  Changing volume level while music is playing produces no noise whatsoever."
 
Part 3 is coming next

I know, I used to live there and they did it more to each other than to the rest of the world making it very difficult for designers in China to ever come out with something and not have it stolen. That still doesn't mean it is ok.

Jalo, great information. Thank you and keep it up! :^)

Jalo, you're close to earning that free trial of the DX100...

To me with JH13 there is absolutely no unit hiss from the 801. The hiss when decoding 24/96 flac happens with about 25% of my library and has been confirmed as an incompatability. It seems that flac is not all the same

 if anyone plans to use Poweramp or Neutron which claims to play hires up to 24/192, I wonder if we can tell whether it is playing regular format (16/44) even though the materials is higher.


Someone will have to check the optical, coax and headphone jack, in the iBasso player, Neutron and Poweramp or whatever.
 
Has iBasso said the headphone-out will support 24/192?  They could be referring to the the optical/coax, right?
 
Either way, expect very subtle differences.

Jsus, Kiteki - that wall of Jinglish did absolutely nothing for my appreciation of the sonic characteristics of the DX100. Please put on your 'Editor' cap before posting anything else of that magnitude - some poor sod has just pulled up this page on a phone and passed out .....


yes Kiteki lol don't do it again.

I think they were joking Lee.
 
Stop stalking me and acting bitter because I denied your love letter like 1 year ago and pretended I was a guy, and recently rained on your whole ASIO versus WASAPI (more bass) parade.
 
Also for the fifth time I never said your Studio V is bad, I said it uses the same DAC as my $20 X19+, that doesn't mean I think the Studio V sounds like $20, for all I know the amp section sounds like 1 million dollars.

One question: The music player 'doesn't use Android's volume control.' However I assume that it does use the volume buttons on the side....?  I would appreciate an early recipient addressing that. It's not a biggie but it would be a bit strange if it does not since this device was designed primarily for music.

The unit plays 24/192 if that is what is loaded, through the amp section to your headphones.
