Got my HD 800S a few days ago. Been listening to HiRez on Cavalli LC 2/Cord 2Qute Apple Mini system. It was very nice, so I tried them on my main Ragg/Yiggy system. I was surprised at the better sound quality, but some female singers are a bit sylabint. More and better bass, soundstage and detail from the upgrade system. Beginning the long wait for a Stratus.
