I bought myself the Monoprice Monolith M1060 and I'm super happy with them. Judging from what you say above I think they fit your sound profile. Unluckely you have to buy them from the US but they are well worth the price! Moving to planar magnetic was the best decision I ever made. From what ive heard the M1060 are supposed to be very similar to LCD2S but alot cheaper. What has to be said though is that the build quality isnt great on them. But I've brought them to 3 lans and had them for over a year and no issues so far.
If you are putting a lot of money towards headphones then buying a DAC/amp is a must and I can't stress it enough. It improves the sound alot because MOBO dacs are crappy generally. Do you have one currently? I'll leave a link below for the one I use and are super happy with.

Edit: I forgot to mention I modded mine slightly by removing the foam behind the "grill" on the outside so to speak which improved the sound quite a bit. If you would be intrested in that hit me up and I'll help you out.
