Headphoneus Supremus
I might be one of the exceptions, but I enjoy listening to my music at higher volumes. To get the sound to the volume I enjoy, the Dave will start clipping and distorting. I have taken my my rig to multiple meets, and others at those meets have come to a similar conclusion. Not everyone mind you. Just my two cents, some will find the synergy just right, others will find it lacking as they turn up the volume.
Interesting as Rob says the DAVE doesn't clip until +4 dB on the volume. I want to be clear that I personally find nothing wrong with adding an amp if that's one's preference. Music is all about personal enjoyment!
