I'm over 150 hours into burn in. Not sure if it made any real difference past 75 or so hours. The base hasn't really changed as such, but the mids and highs have come forward significantly more.
The overall sound of these Denons do not allow for listening at a meet unless you're already a 'sucker' for its characteristic sound.
A lot of the 'lightening' up is psychic.
If you've been listening the Sennheisers and AKGs and then pick up the Denons, you'll be overwhelmed. Even today, I was listening to the Senns to see if I was really enjoying vocals reproduction that much more with the Denons. Sure enough, it wasn't made up. The HD650's have a comparatively 'harsher' and more accentuated midrange. The low mids reproduction is also not as I prefer with the HD650's. It makes for a less smooth and lush reproduction of vocals. On going back to the Denons, I was transiently 'hearing' that heavy bass again until my ears settled right in.
Overall, I have less listening fatigue with the Denons, so it would seem that its signature is more suited to my ears. The base is a tad too much making it certainly not perfect, but the smoothness of sound production is great, one that I generally prefer.
