grabel,
I own the K1000, and I'll probably get a lot of flack for my following statement:
the k1000 are fantastic headphones if you want to hear every intricate detail. but as it is the greatest of open designs, the best way to listen to them is behind a closed closet door, as you will be able to hear all ouside noise (like fans, aire conditioners, bells (microwave), telephones, toilets flushing, people walking upstairs, dogs barking, car horns blowing, crickets, cats making love, babies crying, lawn mowers running, ice cream trucks passing, jack hammers, door knocks, door bells, steam pipes singing or clanking, rain against the windersill, wind howling, children playing outside, neighbours fighting, your neighbour's music, airplanes flying overhead, train whistles, truck horns, refrigerator doors closing, drawers being opened and closed, your wife calling you, people walking up the stairs, people running down the stairs, the pool pump going, birds chirping, cars crashing, iceicles and snow cracking, etc.).
like a lot of low impedance cans, there seems to be a volume threshold where it distorts horribly once you pass that threshold. so i wouldn't classify them good for symphonies (like the 1812) but they should be great for chamber and boroque. and if you did want to listen to the 1812, you would have to find the loudest passage, adjust the volume to below distortion level, or a level which you consider moderate, and then start the 1812 from the beginning. that way you can sit back and relax and not have to run for the volume control when a cacaphonous (ooh, is that a word?) passage comes along.
if you a have lounger, laying back tends to increase the perceived bass.
i love my k1000. but i can't just whip them out and use them whenever i want. i have to wait for just the right time. which is why i have the dt831 and k501 - for all the rest of the time. you listen to the k1000 in total silence. it's something to be enjoyed and savoured, in other words, a treat.
