Headphoneus Supremus
I own both the D2000 and the 7000 - both fully Lawton modded and with custom wood cups - and the sound is close enough to equal for me. The LA7000 is a bit stronger in the bass primarily due to the cups I have on there (Teak from SE Asia) are deeper than stock and the bass is glorious but I listen to the 2000's a LOT.
My memory of the D2k I had years ago was just mushy bass and mids, and very little treble. That Lawton mod must be something to get it to ~ equal the D7k! I would consider my D7k very near to my personal preference. May have to try the TH900 someday, but from what I gather it may not be an upgrade, but a bit of a side grade.
