bought a pair with a blue cardas cable used here at head-fi for $1,000 shipped. price was a reflection of chipped paint/ slight dings. i was very happy to be able to get a pair with a cable that i could afford. this is the best grand i've spent on headphones. i just love 'em.
tons of bass, highs are not sharp, brittle or bright. gorgeous mids btw, these are amazing ear speakers.
my gear is decent (listed in sig) and my source material is very high quality; all of this probably helps. i never thought i'd love a single headphone more than rs1i's, ps1's, ed 9's, ed8's, w3000anv, he-6 and k1000 - but i do. everything i play through them sounds incredible.
i have T1's out getting new drivers right now, and the hd800's are handling all the well engineered/ well mastered/ well pressed and/or needledropped rock i've thrown at them. they are NOT forgiving of even mediocre source material so the T1's will have a place with me; otherwise they'd be unnecessary i think. then again, i like their sound sig a lot and it helps keep things fresh for me when i have other cans to switch to.
