which version of dt770 you mean? I just listen the dt770 premium 250 for 3 days. it has even less bass than the dt880 but more focus (maybe more congested bass)

Good choice.  I like both 880 and D2000 myself.  Do you know if the Denon has more bass than the 770 also?

I used to have Denon Ahd 2000. I've done markl mod however, their bass is just too much for me. Therefore, I ended up with dt880. I drove it through Xbox and Denon cpd. It got some fun factors as I wanted and transparents, balance sound signature . the dt880 also makes my sr225 to be boring and lifeless :-<

I can't believe I'm going to ask this, but...
What kind of amp do you have?
The 250 ohm version can be difficult to drive.
 
There shouldn't be, AFAIK, a reason why your 770 has less bass than the 880.
My version was the 32ohm DT-770.  I A/Bed all of them, and my conclusions fit with most Beyer users. 
It's possible you had one of the mixups happen to you with the cans.  I think it was something about incorrectly switched earcups, but I can't remember.  There was a thread about it recently.

Nice I also agree than it makes the lesser Grado's sound lifeless or boring. I loved the DT880 but sold my set.
 
sugarkang, my DT770 also has less bass than my DT880. Both are the 600Ohm models.

I think this explains it all quite nicely.  I love the 32 ohm bass.

Graphs are not accurate at all no matter what. When I heard the 32Ohm variant on my X-CANV8P it still had less bass than my DT880/250Ohm.

Well, that one seems accurate.  My 32ohm 770 had the perfect bass I thought.  More than my 32ohm 880, when I A/Bed them.  It also makes sense by matching with your 600ohm version as that has less bass than both.  In my experience, the graph has always seemed quite correct and I used it as a measuring stick for EQing my cans to the Denon.  It helped quite a bit actually.

It would be good if you gave them all a listen.
I found the D2000s to have a hollow mid range and was quite dissapointed in them.
I also found the DT880s and DT990s to sound almost identical. They are clearly way ahead of the D2000. 

 

[sugarkang]

I found exactly the opposite.  The D2000 has bass that is deeper and far away than what the Beyers or any other can provide (that I've tested so far).  I also found the 880 and 990 to be somewhat similar, but still noticeably different, particularly in the 990's bass and treble output.  That's all subjective of course and isn't important to the buyer.  You're right because he should try to A/B them himself.

I am planning to drive the dt880 250 by ibasso p4. Because it has 12.6 voltage swing, also opamp rolling option. Any other recommendations?

You know it's odd... my DT990 no longer has the big bass it once had but now is quite lean sounding. The T1 now has more bass than it... Perhaps something went wrong with the drivers?

I take it that's not supposed to happen?
