I've had the D5000 (J$ pads) with my 160D as well as the LCD2s. 'Better' is not a descriptive term for what you can expect.
You lose the fun low end punch and sparkle up top of the D5000's. You can gain a lot of clarity in the mid range and a more natural sound with the LCD2. If you've grown used to the Denons the LCD's may come off as boring by comparison.
I suppose by hifi standards here, the LCD2 is 'better' on all accounts.
Thanks man i was afraid of that because when i got my d-5000 it was for the bass. i chose them over senns 650. Grados, and Stax's.
