So, I always see a great deal of high praise for 1000m's; and though I haven't heard them in person, I'm sure they are worthy of such. However, I am an owner and lover of NS-500m's. I'd like to know if anyone has done a direct A/B comparison of these two, and if so, how do they compare sonically? Given their relative market value (and there is quite a spread), if you had to choose based on dollar value and sonic value, what would you choose? Just curious, I've wondered this for quite a while now.
