Not to be a PITA, but it depends on your definition of "equivalent."
I think Dave addressed it,
The D2 is a "unique" flavor, even amongst Dave's own offering - to some degree -- I dont want to put words into his mouth but, that is my take after reading about it and listening to it.
I just replaced an IC I found very nice and neutral, but I Think the D2 offers things that suit my system (warmth, in an emotionally involving, toe-tapping kind of way that does not make me feel like I am compromising detail),
So I was kinda asking if his PCs did the same,
and he kinda said yes, but kinda no...
I want sweeter, smoother and MORE BASS. Some PCs do that, some are more neutral or detailed, etc.
