Thanks for the scans. Interesting thread. Can anyone explain to me, qualitatively, the difference in sound quality between the 690s and the 1000(M)s? I hardly ever see the 690s here, although I see 1000Ms with some regularity, and some of the other (smaller, lesser) models.
I'm a little surprised to read of so much love and respect for the 690s vis-a-vis the 1000s. If you already have the NS-1000Ms, and could easily get another pair (which is my situation), is there any good reason to try to find the 690s? Would they offer anything better than the 1000Ms, or anything different enough to be worth getting them for? If so, what?
