I've just had a Sony NW-HD3. Very happy with it. Problem- I don't seem to get anywhere near as much bass as a once did with my old Sony Walkman CD player with bass boost on. Using thensame earphones (Sonys best in ear ones) I've tryied the EQ and the "Digital Sound EQ". I do wonder if the format i'm using "ATRAC3PLUS- 64kps" could be redusing the number of possible sound frequices in my music? Could i be used to too much bass? Can anyone give me advice?
