My friends Astell&Kern AK100 (aka iriver-rwa-ak100) stopped working, and I think the battery finally has died. The battery has the following markings: PR-665354N F121 00701AA 7.4WH 472246454746 3.7V 2000mAh. Li-ion battery. All links I have found (on this forum) seem to be dead, so if anyone...

Hey folks , my 25th pair of earphone (i'm sure there are folks here who had 100s ..lol ) just arrived this morning delivered to my doorstep.  Anxiously ripping up the parcel,  I was almost late for work.   Here it is !   Woodbolt Earphone (handcrafted rosewood ) from Apollo Audio Lab.  ...

Hi all! I'm pretty new to high end headphones and am thinking about switching to a pair of IEMs (because at school I can't always have a hefty pair of over-ear) and I have two ideas. 1)buy a good quality westone IEM and run it through my laptop or 2) get a pair of etymotic IEMs and a...

Would be awesome if someone could do a head-to-head comparison of these two with the same IEMs/headphones and the same song. This if for anyone who has both.  Pono is looking very enticing for me as I will be buying my first source device, it's way cheaper than the AK100/120 and many say it's...

I have very new JH 16 3A set up with AK 100, what is a fair price for the combo or both.   thank you,   Rob

Hi all Head Fier friends 30 minutes ago my long awaiting Stax Sr 002 and Srm 002 has just arrived I with another 10 friends are doing the audition now I will update later , on my first impression Here's the picture on the session , the guys are enjoying the audition, Setup as below ...

Hello, Now I am in searching for  the new pair to Westone 4r ( with silver cable) and have some doubt about player. There is only two candidates  1) Colorfly c4  2) Iriver ak100 Is there is any difference between them on westone?  Have tube amp at home with "home headphones" ( Have read...

Ok, i researched a lot, and i narrowed it to this. I'm looking for a closed back over era headphones, it needs to have good mid and bass, acceptable treble and really good isolation, and most important, they have to be really fun. My source may depend on the price of the headphones, if they are...

Please share your impressions here guys...

Holy Crap. Iriver and A&K pulled it again!   New AK100 and AK120. This is not AK100 MKII. http://www.astellnkern.com/eng/htm/ak100/ak100_2_spec.asp   Balanced DAC with low impedance. New 64gb storage. Fresh design

Hello guys. Is there a significant sound quality difference between AK100 and AK240? Also, how would you compare their sound to Ipod Classic 5.5 gen? 

As the topic suggests, I have a pair of JH Roxanne's that I am currently using in conjunction with a Iphone5...I am a subscriber to Beats audio app and love it (this is similar to lose less music, correct?) and am looking to upgrade my dap to bring out the perfectness of the Roxanne's I'm not a...

About Myself: (I can review anything, if I am provided with the product :p) http://www.head-fi.org/t/674373/story-of-a-new-reviewer-kimvictor/   Intro: The AK100 isn't a new product, but I've been noticing interesting trends on head-fi to either hate or love the AK100. So, I though I might aw...

Which combo would be better suited for iems? Don't necessary require a lot of power.   My main priorities is to have no background noise/hiss at any volume, channel unbalance (at low volume) or IF interference when outdoor.    I already own the Fiio E11 and using it with a L9 LOD to my ipod...

Hi, the market has just exploded in the last 18 months, quite hard to cope with it all. ( I use ES10s (with ESW9 pads) and DT1350 only on the move,)   My 801 line out collapsed on me today, the headphone socket broke months ago. I have asked Head Direct if they can do the repair, but I am not...

Hi all,     Long time lurker(10+ years?), and gonna land in the poor house (with nice gear :D) because of it. Anyway, I picked up the AK100 (and will be sending to Red Wine since I have both TripleFis and Shure 530's :/).   I loaded up the crappy iRiver software (compared to Media Monkey or...

Hi folks,   Starting a new thread as I actually don't see one on this topic. I'm beginning to look for a portable digital audio player of some kind with a good DAC inside it and can hold (and play) 160GB+ worth of hi-res music files, be it via flash memory or otherwise. So far the only choice...

Hi All my head Fi friends Please share your low End to high end DAP opinion , impression and appreciation here . In between 3 years are so many low end to high end DAP from all over the world coming to serve portable audiophile Sound Quality fans . I would like to make this thread , that all...

I realized that I should have asked this here rather than the Intro forum.   I have an E12 and an Alo National en route as my portable amp solutions - but I have realized that i want a portable with a juicier, more tubey sound: warm, velvet, lush, rich midrange.    I dont care if I cannot use...

Hi,    Could somebody help me out?   I love the sound of my AK100, drop dead gorgeous......BUT.....i prefer a more shuffle working device.     Thinking of trading it for the RWA Imod where i can install Rockbox...but not sure if the wolfson chip has the same quality?      If this is a...

my zune hd is on the fritz and i was looking to buy a cowon j3 32 gb but after a few mins of research  i found they have stopped production and that most cowon products are not doing well, i was almost about to buy an itouch and said f that.   all i need is   32gb+ (maybe an added sd slot...

Hi guys, I need some advice from the community. For backgrounds, I own a LG G2, Mac book and they are what I normally use to play music. I have a pair of Minera Mi-1 which I have been using for 2 years and I have recently got a pair of Unique Melody 3DD and have recently starting to listen to...

Hi guys, I'm looking for mobile earphones or iem's to wear on the street/transit with iRiver AK100, I know it can be a bit tricky as the player has 22 ohm on the way out. I picked a few iem's below, maybe someone tested some of them with ak100 and finds it working quite well with no sound...

So, if anyone was following the AK100 tread, I've decided to mod my AK100 myself. The cost of modding, if done by RWA or MS, is $250. That's already bit too much and considering the $80 shipping to RWA and $30 shipping to MS(I live in Korea) as well as the wait time and possible customs issue, I...

Hi guys, I have am stock AK100 that I am looking for IEM recommendations for please.....I currently have a pair of Tzar 350 and Aurisonics ASG1.2 but was wondering if there were any alternatives worth trying out which are potentially more all rounders (Shure are out as I don't like them). My...
