I think my celing is the LCD-2. It blows my mind everytime I listen to them and it's been 2 years. Had my drivers replaced in October of 2013 and they're better than ever. If the X and XC are even better, they are completely unnecssary for me as I would probably lose my mind and all sense of time and reality, wake up deaf 10 days later with drool and vomit all over my shirt wondering what the hell happened after I hit play.
Oh, hold it, aren't you the guy who's spending everyone else's money? C'mon, we know you want one, I'll bet you can get one for less than $1800, brand spank'in new ($1799). You can get your shirt dry cleaned and still have enough moolah for a new amp.
