I can't say as regards the LCDs or HD800s or other good quality alternatives. I did hear the HD800s briefly at a hifi show and was not impressed at all.
I know many have said it before, then started again, but I have stopped looking now. My 009s and my (recent) KGSShv with NOS DAC is cheer heaven. I can't imagine better.
Or until I hear the 0011's ha ha!! Lets hope if they ever surface, they don't look like the back end of a donkey.
