I used to own a K1000 and I remember that it had superb "outside the head" imaging. I sold it a while back. I just picked up a Hifiman HE-500 and I'm impressed with the imaging, and it does get "outside the head" and feel "open" almost to the degree the K1000 did, but it's been a while since I heard the K1000. Does anyone here own both a Hifiman ortho and the K1000 and have any immediate impressions of the imaging of each?
Had the HE6 on loan and have had the HE500 for a while as well as two K1000. As much as I like the HE500 the K1000 is IMO a whole different beast and the one I prefer. Granted we all hear differently and our music, sac, amp, etc can steer us into different directions. Just try it and decide which is better for you.
