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 16? load and 130mW(!!!) into a 32? load. I wanted to verify, if that's true.
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.
Oh, you have crushed my dreams... So with Cube's amp it's all a lie? They even advertise in official press 130mW of output power. Eh...
I think I have to revise my headphones choices a little, but multiple-drivers balanced armatures can be quite difficult to drive, because their impedance is changing with frequency response, sometimes drastically.
It all comes to this, that there is in point in buying a DAP other than Clip+/Fuze, if (objectively measured) great sound quality is needed, and the possible difference is 3dB in loudness, which is almost negligible. I don't know anyone, who listens to music at full volume. The market is drifting towards making DAPs another smartphones with big displays and touch-everything.
