Hi Matt - that's a useful impression for me to hear as I decide on a new Audeze.
About 6 months ago I decided it was time for some serious headphones. I set my heart on the LCD2s and began reading about them on Head-Fi while I started putting money aside for them each month.
Perhaps this is normal for any revised headphone but the Fazor/Non-fazor versions seem incredibly polarising and varied - they range from people who think they are a tremendous improvement, to those who strongly dislike the change in sound (like Matt's post above) to a great many who state that the difference is subtle, difficult to A/B and not one to lose too much sleep over. Finally, I just read Mike Mercer's product of the year review for the LCD2F... I don't think it could really be any more glowing.
It's pretty confusing. In the end, with the difficulty of demoing the different versions here in the UK, the lack of a strong used Audeze market here and the high price of used equipment that comes from the US (once you factor in VAT and customs) , purely on cost and value, the sensible option seems like a new LCD2-F at this point.
My only worry with them, is when I hear people say they are too bright which really turns me off as that kind of sound is just not for me. Getting back to the EL-8 - If it is brighter still then I think i'll skip that one. It does sound like a great headphone and its great to see them continuing to push the boundaries.
All the best
Jeb.
