The Gr10, like most MAs or BAs have a rising impedance in the highs and will have a corresponding rising high frequency with an output impedance likw that of a stock AK100. All your other phones are single driver dynamics which are generally flat impedance. The RWAK100, clip, Ipods would not exihbit this in a noticable way even if they are not as good in other respects. It would be very disappointing for someone whoes favorite IEM was say an Ortofon EQ-7, GR10, TF-10 or any Phonak etc.

Based on what I have been reading about this unit, and believe me I have read over 5 different detailed review and seen the videos where the unit is having problem playing flac as soon as its screen shuts off, everything is pointing towards this product not been worthy of that price.

 

In particular where most people prefer to spend $350 to mod what is already an expensive unit. I meant no disrespect to the people who have made this or the people who love this product so dearly, it is just as a consumer my first priority is to think about my own self and my wallet :-)

 


Is this graph based on what you perceived or with some testing done?

 

If you just look at the table and focus 'only' on the SOUND, it seems the AK100 (even with the pico) doesnt sound close enough to the ipod connected with fostex & clas solo.

Is this true?

 

Also where does DX100 come in here?

 

Thanks

This is not my graph, someone else posted it here and I used it. I am also wondering about this graph myself.

As I know before AK100, there were several portable audio players with Wolfson WM8740.

 

Teclast T51 uses two WM8740 chips.

I suppose this could be related to the high output impedance.  The thing though is that it seems to be having greater problems with the low frequencies.  It seems to "growl" and generally sound very rough in the bass range.  The higher frequencies still seem very bright and clean.  

 

Strangely, the gr10s actually sounded better when i first got the ak100 about a month ago.  It is also possible i damaged them.   The 262s require more volume to drive and i forgot to the lower the volume a couple of times when i plugged in the gr10s.  I am actually hoping  that it is related to the output impedance issue because i think they are now out of warranty.

Hey guys, it is my graph......
My AK100 was purchased from CHINA,
Pre-ordered and mine is the first MADE IN CHINA batch, not MADE IN KOREA batch.
So it is cheaper. In HK, the price was about 550+ usd but the distributor was suddenly replaced by another under Iriver complaint (they set the price too low).

Honestly, the power n quality of AK100 cannot match the IPhone + Fostex hp-p1,
I have all the set up in the chart more than half a year, tested with many iem n headphone like srh1840 n w4r.
But comparing the functionality, cost n performance, AK100 sound quality is very stunning already. I am a mechanical and production engineer, I find a product like AK100 price tag is normal.

AK100 is not an iPod that can be mass produced a lot for a huge market. Audiophile stuff generally are luxury stuff, not groceries. I won't expect it to be always "budget friendly".

I was actively discussed about AK100 in a china forum, but some ppl keep magnifying the cons of AK100 and the flaw of AK100's back glass which was not glued to the back flat enough. They always comment that AK100 worthy of $200 only. I think it depends on how much you are willing to sacrifice for such type of device, u don't like it you can say it worth a few cents only. But for the design, built, soft n hardware, from a business and marketing perspective AK100 just slightly overpriced. Come on which Luxury product is not sort of overpriced? It is not a Fiio X3.

For the sound my iPhone + Fostex costs about 1000 usd, AK100 just almost half the price, much portable, longer battery life and 85% sound quality. I do love this device so much.
These few months I listen to AK100 + pico slim or I basso T5 with my Beyerdynamic dt1350 / pioneer se mj591 / w4r almost everyday, the convenience it brings make me able to enjoy my music freely, the price tag of 650 is still acceptable to me, I even want to get a spare one but know that there may be AK200, HM901, so I lock my wallet away yet.

A few things to add,
Most my friends and I who have AK100,
The unit works fine all the time,
If the unit is faulty you can always return for replacement.
The sound quality is really great, but it is a very subjective issue.
I think some folks just don't like its sound signature.
AK100 is like a stealthy agile ninja assassin,
iPhone + Fostex is a versatile and sophisticated GI, both can kill professionally but just a matter of taste.

What I care is how the firmware will improve.

Hmmm... Would there be a difference in the made in china vs made in korea?

Virtually no, i tested my friend's. Ak100 and the ak100 i found in tokyo bic camera, checked the outlook also. I see and hear no difference.

Simply, if you got the money, want a device of long battery life, all formats supported, smaller than pack of cigarettes, nice sound, smooth ui, go for it to enjoy asap.
The ui is better than the cowon c2, d3.
Card content scanning is fast.

Nonetheless, if you want top notched sound,
You should go for hm901, but it is 1000USD.
Its charging has some trouble issue, much expansive, less portable.
AK100 is the best or most desirable dap i want so far.
The huge capacity is more than a plus to me,
Coz i now can have 5000 music or songs in it, a mobile jukebox of 32+64+64 gb.
Later with 128gb card, it can be close to 300gb!
It provide something other dap can't do, just BUY IT AND ENJOY IT ASAP, life is short.

There's also the RWA mod option so keep that ib mind too, especially if output impedance bothers you smily_headphones1.gif

My Tera player is having more "me time" now though... Love that thing to death...

Love that thing to death beerchug.gif

 

I only have "Copper Ears, not Golden Ears", so I found no issue with the Impedance...

Even for impedance issue, I don't worry, I got all my amp with me to solve it. (pico slim, ibasso t5, corda stepdance....)

 

It is not easy to find the "Right One"... Luckily I found it!

Now at this moment I am listening to AK100 with my SRH1840. (No amp) 

In Heaven Now...

Personally I have done audition for ipod Classic(7th Generation) + Fostex H1P1.
The Fostex H1P1 has really improved the sound quality of iPod Classic by making the sound stage/3D imaging very much wider & open. It also help to improve  the vocal/instrument separation crystal clear. The downside of Fostex H1P1 is high cost and the internal amp is a bit weaker. But if you use Fostex H1P1 just as DAC, then it is a very excellent device!
