re: "Finally, has anyone compared and listened extensively to the K1000 and K701s? Any comments?"
no comparison. the k1000's are in a league nearly of their own. but it's like apples to oranges in presentation as the k1000's aren't against your ear.
that said, the 701's are great for the money.
THAT said, if $ is not an object, the Grado GS1000 blows away the 701's in every way possible. they ARE in the same league as the k1000's, but again, it's apples and oranges.
