״So, the iPhone 4S wins yet again, providing almost the same experience as a dedicated $130 headphone amp -- which is pretty incredible when you think about it״

פלוס:

״The DAC inside your PC is not implemented in the same way the DAC on your iPhone is. People are always surprised at how good their i-devices sound, which is strange because the device was designed for music originally. Most i-devices have good to great DAC chips in them and a decent amp stage ( for a portable ). With uncompressed files you would be hard pressed to hear a huge difference between say an iPod and a good home stereo system."

הכל שאלה למה משווים.

באופן כללי הסאונד של אפל יחסית מפורט אבל עם באס מודגש- אני מאוד לא אוהב. אפשר להרגיש הבדלים עם אוזניות טובות או מערכות היי אנד, לא ברמקולים מוגברים ב700 שקל.
