Hi everybody, maybe I can start by saying that this forum ROCKS, I already found tons of answers to most of my questions, just 1 left. It concerns the european Nh600, which I bought yesterday and am quite happy with, but...... The sound that comes from this gadget literally sucks compared to my old MZ-R90 which I've used until now. The quality is significantly lower (no richness whatsoever) and so is the volume. It also seems like the maximum volume is limited and when you reach a certain volume level in a song (for some that may be at vol.20 for others at vol.30) the player just won't go past it! As a result, you can up the volume all you like but generally when you go past 25 the actual volume just doesn't incease anymore :-(. I've messed around with the acoustic engine and upped the bass a bit, which helps the quality a bit but is also seems like it lowers the max. volume "threshold" as well. (I'll call it that for lack of knowledge of a better word). So my question is: Is this different on the more expensive models like the NH900 and the NH-1? Do they have more powerful outputs? Can I Hack the default output setting in the service menu and up it a bit? Thanks in advance for your help.
