I have LCD2 rev1 and recently switched from foam headband to the leather one and the fit is much more comfortable for me. You should check to see if the screw on the hanger is tight also. I check my every few months as they loosen over time and wiggle down a bit. I get them set on my head so they are the most comfortable, and then I take the screwdriver and tighten them down tight, so they barely even swivel. It keeps them in position on my head really well and I wear them 4 to 8 hours a day while working.
Also, if you have not bought a DAC yet, have you looked at the Audio-gd NFB11.32 DAC? It is a 32 Bit USB/32 Sabre DAC/Amp combo and I bought it a few weeks ago and I have fallen in love with my music and LCD2's all over again.
The DAC/Amp is very detailed, and revealing and it added the details in the highs that the LCD2 lacked and have produced a more well rounded, smoother sound that my previous setups.
The most recent setup was a Violectric V800 DAC and V181 Amp. A balanced setup that went well with my 4 wire Norse Audio Cable, but the NFB11.32 in single-ended sounds much more enjoyable than the Violectric setup did.
Before that, I had an Audio-gd Ref5 DAC with Woo Audio WA6SE Amp with the LCD and that was dark, lacked dynamics, and power and was just too underpowered for my tastes.
A note of warning though, the NFB11.32 does not have an analogue input. I too have a vinyl setup and I am stuck now looking for an amp for the setup. BUT, at less than $400 for the NFB11.32 (with the TCXO crystal option), compared to nearly $2,500 for the V800 & V181 setup, I don't mind getting a tube amp for my TT setup.
BTW-What Phono Stage are you going to use? I have the RSA F117 Nighthawk which is a battery powered phono stage from Ray Samuel's and I can vouch for the sound quality from it. I have a ProJect RM6SB with Sumiko Blue Point Special Cartridge and the F117 is very revealing, and very black background.

Hope this helps you. It really made my LCD2's sound more like the HE series from HifiMan with the added benefit of bass dynamics that I think you will sadly miss with your dub step ( I have listened to the HE5 and HE6 with my setup and others and I really like the mids and highs on them).
