I had one on loan for a long time. I also had one that I bought for someone else and modded. Never had one of my own until now. It's in good condition except earpads and screens, both are dirty and worn but still have a bit of life. I can wash the screens and might make custom lather pads in the future after I mode them.
I also like stock YH-1 just fine, but my modded one is much better. If only they did not become so inefficient after damping.
