These are my five best performing headphones that I've used so far.
1. Sennheiser HD540 Reference II
2. Sennheiser HD560 Ovation II
3. Etymotic ER-4S
4. Sennheiser HD250 Linear I
5. Sennheiser HD540 Reference I
I intend to try the AKG K1000 soon, which will probably take first place and shift everything else down a place.
A vintage guy I see. Good luck with the K1000.
