Coming up on 100 hours of burn in with the HE-6. Noticed the mids were sounding a little reserved and the drums and cymbals were recessed. Looking at the leather ear pads I noticed how dark the cloth was that covers the drivers. I swapped them out for the vegan pads with a thinner driver cover and voices and instruments (especially drums and cymbals) became more transparent and present. I just love these phones. They are my signature sound to a fault. Goodbye Audeze LCD-X and Sennheiser HD 800.
Mine arrive in two weeks — we'll see how I like my HD800s by comparison. I'm especially exited to hear the HE6 render piano. It's a tremendously difficult instrument to render convincingly, and I haven't heard it reproduced to my satisfaction. Short of electrostatics, HE6 was my best bet.
