The D7 can play pretty loud despite having 85db sensitivity but you need to have atlest 50 clean watt, meaning more than 50 watt pr channel and it has a really good tight deep bass (use isoacoustics stands) even at high levels as long as it's clean watt and not the hardest edm.
If not denon, audiolab 6000a might be a good match, 50 watt is okay but sweetspot is 80-125watt in 8 ohm
Even wharfedales Diamond 225 can't keep up with the bass, it might have deeper bass but not as much, many times the 225's sound thin in the bass, even when the highs are not loud you often feel the need for a subwoofer,not with the d7
Roberts (metallica) bass you can easily hear, it's not limited in hz like the Harbeth P3esr that sounds thin in the bass not matter what video i listen to.
wide soundstage and you have to play either really loud or some nasty recorded music for the high midrange to sound screaming, not just loud (a little easier when using them for near field listening)
The hight are to not loud and intrusive, unless it's how the music is recorded (or bad system)
Using them for my pc close to a wall
Tight punchy and loud
