Dear Sirs and Madams,

Is it possible that one of you, with proper equipment, could measure Cowon E2's and/or Cube C30/C60(a.k.a. Nationite Naninte N2)[they are using the same hardware] maximum output powers and post their results? It would be great if you could rate output impedance and frequency response also. It is nearly impossible to find such information on the web.

I would greatly appreciate it. Thanks in advance.

Andrew

Firstly, thank you for your reply.

Secondly, I find these DAPs quite popular, with price around Clip+ level, in the area where I live, which is Poland.

I know it is very hard to find that kind of information. I normally rely on nwavguy's blog(for technical knowledge), http://rmaa.elektrokrishna.com site(for more specific players info) and other hidden somewhere pages.

I am asking about so specific information because, as I've read, Cube C30/C60's amplifier( http://maxim-ic.com/MAX9722B ) is capable of producing 70mW into a 16Ω load and 130mW(!!!) into a 32Ω load. I wanted to verify, if that's true. It would be nice to use it without external amplifier, which I don't own nor I need one now, but I would like to buy more power-hungry headphones in near future.

In regard to Cowon, my friend is saying that this player was capable of driving, 250Ω/96dB sensitivity, Beyerdynamic's DT880 into usable sound level. I find this very hard to believe, even Cowon site says that this DAP produces only 12mW into a 16Ω load. I would like to verify this as well, for the reasons stated earlier.

Using nwavguy's guide to "power" ( http://nwavguy.blogspot.com/2011/09/more-power.html ) these DTs would need around 12mW of pure output power to be driven into peak SPL of 105dB. And E2 is producing only 0.7mW into 250Ω load, of course accordingly to manufacturer data.

And the reason I am asking all these specific questions is, that I would like to buy something more powerful than Clip+, which I currently own, while keeping almost perfect sound quality and without all "bells and whistles" found in Cowon J3, D3, Sony X10xx or any other smartphonish-DAP.

Cheers,
Andrew
