I thought this might be useful, at least as a starting point for some people. I know I've wondered about it. Obviously it isn't comprehensive but I'll be happy to update it as additions come in.

Per channel at 16@ohms

Cowon D2 = 37mW
Cowon F2 = 30mW
Cowon 6 = 30mW
Cowon U3 = 30mW
Cowon X5 = 20mW
Cowon M3 & 5 = 20mW
Cowon F1 = 18mW
Cowon G2 & G3 = 13mW
Cowon A2 = 32mW
Cowon iAudio T2 = 23mW
Cowon iAudio 5 = 13mW
Cowon iAudio 4 = 13mW

Creative Vision NX = 25mW
Creative Vision M = 30mW ?
Creative Zen = 30mW
Creative Zen Nano Plus = 12mW
Creative Zen V (Plus) = 12mW

iriver H300 & H100 Series = 20mW
iriver clix = 15mW
iriver U10 = 15mW
iriver S10 = 15mW
iriver T10 = 15mW
iriver T20 = 15mW
iriver E10 = 18mW
iriver H10 = 18mW
iriver T30 = 15mW
iriver iFP700 = 18mW
iriver X20 = 13mW


iPod = 30mW
iPod Nano = ?
iPod Shuffle = ?

Meizu M6 = 18mW

Rio Karma = 55mW

Samsung YP-Z5(F) = 22mW
Samsung YP-U2 = 20mW
Samsung YP-T9 = 20mW
Samsung YP-K5 = 10mW
Samsung YH-J70 = 20mW
Samsung YH-925 = 12mW

Sandisk Sansa E200 = 40mW (I find this hard to beleive, I had a Sansa, it did not drive my CX300s well)

Trekstor Vibez = 12mW

Zune = 30mW

I have one of the original Zen NX's and the power output is quoted at 50MW per channel at 32 ohms for a combined total of 100MW which is what the Xtra is as well and I'm sure the original Zen.

Also, I think what you'll find that your Cowon D2 numbers are based on a combined amount. Cowon D2 47 X 47 MW. In other words 47MW per channel, etc and the Ipod is 30MW per channel. The Zune would equal the Ipod as would the karma on a combined total. The karma is quoted at 55mw per channel at 16 ohms and 30MW per channel at 32 Ohms.

Wow, that's a lot for the NX!

Correctios made.

Sandisk Sansa E200 = 40mW per channel @ 16Ohm

From http://www.portalplayer.com/products...rief_Mar05.pdf

 

[sgrossklass]

The G3 spec should be for 16 ohms, at least it says so in my manual. (Still goes plenty loud enough with 600 ohm cans, so the 13+13 mW may well be an understatement.)

 

[Denim]

Another addition for your list:


The Meizu M6 --
Earphone's Output: (L)18mW +(R)18mW(16 Ohm)

 

[Superbaldguy]

I have yet to find the Nano's output specs - any guesses?

There may not be a direct relation between output power and sound quality. For example there is a bass roll-off with low impedance headphones if the output capacitors are rated too small, regardless of power output.

Unless a player's output is very low, it doesn't matter much (with efficient portable headphones). For instance the CX300 needs 6.25mW for 102dB output. You can listen to music at around 82-92dB average with those 6.25mW and that, in my opinion, is very loud.

 

[Gurra1980]

This is the correct specs for iriver.
At 16 ohm, left, right.

iriver clix 15+15mW
iriver U10 15+15mW
iriver S10 15+15mW
iriver T10 15+15mW
iriver T20 15+15mW
iriver E10 18+18mW

That may be but from a non-technical view my Dell Pocket DJ drives the CX300s much better than did the Sansa. I should have also clarified by saying I was referring specifically to sound output (loudness) not quality.

It would be quite strange if Sansa's output wasn't loud enough for CX300. I just did a quick test with my ER6i which have 6dB higher sensitivity than CX300, but also used MP3gained file (-10dB). At near maximum volume the sound was extremely loud and unlistenable (probably not safe either).

It could simply be a few things:

- my ears are better than yours

and can handle more dBs
- your ears are better than mine

and I'm partially deaf from listening too loud
- I'm totally mistaken and I didn't use my CX300s with the Sansa but my Porta Pros. You have me wondering if I'm mis-remembering it (this was back in April).

Thanks.

 

[breez]

H100 has almost the same hardware as H300 (same sound chip) so that one is 20mW also.
