Does that PDF hint no gap-less, or... ?!

well sorry but if the output impedance is 22ohms, I dont care what they say, it is NOT suitable for IEMs, particularly multidriver IEMs, since due to the crossover they can present less than 10ohms in the bass, even those like my jh13 that are rated at 28ohms nominal. this results in an uneven power response vs frequency

Look, stop being ridiculous. I've been listening to mine all day without incident, enjoying how it sounds, trying a variety of genres out... chilling out to some female vocals, some nasty bass lines, some widdly guitars... it's a bit of niche consumer electronics, not an identity crisis in a box.

 

Just turn the bloody thing on and listen to it!

Is he talking about an ipod? ha ha

I gave them a call today and the guy has not even heard about it.

He also said they don't really have that much to do with iriver anymore.

check here. no matter you can read korean or not... there has enough graph to see

and price in korea is around 580usd

Thank you for that. Cowon S9 output independence is 2.17 ohm and iRiver AK 100 is 22.41, so that mean is i use my Westone 4R this won't sound good?

i think it is not about good or bad, but will change the sound signatual

check 05 impedance and phase.

 

if u change device s9 to ak100, based on what they said you gonna have lil bit more midhigh and bass(below 100hrz)

Goldenears are really quick on measuring new product:) .Good looking graphs. Hope the it will sound as it looks

Higher output impedance generally means the frequency response will not be as intended by the manufacturer on lower impedance earphones, especially those with nonlinear impedance curves. It could change sig and become less balanced. Don't know about the s9 but the I9 shows bass roll off on low impedance devices even though it's output impedance is in the acceptable range. Likely uses too small of a DC blocking capacitor at the output so there's always more to it.

 

If the output impedance measurement is accurate on the AK100 (RMAA can be fooled), I'm pretty disappointed in the result. It may be acceptable in many cases but when you design leading edge and upmarket product, why make this big of a compromise. It would be easy to design in a lower output impedance. If true, this is a major oversight and disconnect in the planning or design phase. I had high hopes for this one and now my interest if waning.

This is really strange, on the official release photo the iRiver logo on on the front of the player, now is gone?

Who made this after all?

Sad that it is 22 ohms. That is ridiculous. How can they mess up on something so basic.....? Wonder if  they will address this before releasing the player because this is not acceptable. Come on what do you think the main crowd for this device would be for? The portable crowd and most of which is sensitive IEMs, not headphones.... Leave the full-size headphones at home ;).
