Thanks guys. Honestly I would not be interested on the 805D (if they were to exist) as they would be much more expensive than the 805S I guess.
As you now, the main criticism to the N805 is often related to bright highs, and I tend to agree with that perception, basically that's why I'm looking to upgrade to the 805S, hoping that these have a little more gently highs.
Any other comments will be appreciated. Thanks
