Small makers like iBasso and Fiio sometimes do, but I've never seen Cowon provide it for the J3.

cowon actually mentions that 16 ohms is the limit for j3

 

man ibasso at 1000 dollars isn't even affordable(newer one)

I know :
Some people are Lazy to do a research !!!

 

Some people are annoying in every thread. Go back to your Tera Player thread!

1) Perhaps you could try doing some 'research' by looking at when this thread was started?

 

2) Please show me where the output impedance is stated in the J3 specifications on the Cowon website?

I don't really care now, since this thread is 2 years old, but you're being quite insulting, musicday.

 

 

.

I've never seen the OI measurements for Cowon players anywhere, but they've always been noted for bass roll-off issues with sensitive IEMs, which would make me think the OI is higher than it should be. I don't use IEMs myself, but I've always found the Cowon players to power 32-64 ohm headphones very well, and in particular they really make my HFI-780 sing.

Thanks for trying to be helpful, but you're misunderstanding the specification. The '16 ohms' Cowon mention is simply the standard parameter for measuring the current output. So, they are saying that, when measured with a resistance load of 16 ohms, the player can deliver 29mw per channel. If you put a different resistance load on the player, it could yield a different current (mw) measurement, but most manufacturers choose to measure their players with a 16 ohm load, so that everyone can compare players to each other reasonably accurately.

If you are interested in iBasso players, they also make the DX50:

Thanks, Achmed, I actually don't care anymore, since I started this thread 2 years ago (it just got resurrected today, for some strange reason). At that time, I still had UM Miracle, which sounded totally wrong with the J3, because the output impedance of the J3 is evidently too high for the low (& reactive) impedance of the Miracle. I still don't know for sure what the J3 output impedance actually is, I just know it is surely too high for such low-impedance CIEMs.

 

I now no longer have the Miracles, plus I will (when I have the funds) be buying a better DAP in due course. I did actually have a DX100 for a few months, and that sounded fantastic.

 

Anyway, cheers for your input here, and I'm sorry you got caught up in the previous couple of posts.

 

All the best.

Hi, Mython -

What happened to your DX100--did you get rid of it? What were your reasons for doing so? You say you'd like a better DAP; which others are you considering?

Thanks,
Brian

Going through a rough time in life, this past year or so, but eventually hoping to get back on my feet, which will include getting a decent DAP (and CIEMs) again. There's no one DAP that covers all the bases for me, at the moment. Sony NW-ZX1 looks nice but not powerful enough. Fiio X5 looks promising, but may not have as much grunt as I was hoping for. DX100 sounds excellent but it's a brick and I hate having to remove it from my pocket every time I need to change a track, plus the battery life is appalling!

 

So, the short answer is that I don't yet know what DAP I'll end up getting. Time will tell... :wink:

Here is a list of output impedances from sources and amps

http://monoadc.blog64.fc2.com/blog-entry-99.html

A cowon is listed there at 2ohm.

I also recall he who shall not be name wrote on his blog that the j3 was 1 or 2 ohms ( from memory).

sansa clips are generally around 1ohm OI.

then whats the point in spending so much if it can't even drive multi driver iems??

 

this is fraud

Yup, I wouldn't buy one even if I had the money for it in my hands.

Ak120 is 3ohms.

Original AK100 is as noted above and on the link at 42ohms OI, which is why people got theirs modded to 1ohm.

There is a new version of AK100 released at 3ohm which is only Japan release so far, so i guess A&K have been listening.

then all these ppl who buy these are also grtting external amps!!!

 

after spending 800-1000 dollars on these players??!!

 

this is awful..........they ought to get ibasso d100......
