I couldn't agree with what is quoted below more in regards to the 805s. In fact I agree spot on with most of Wrightstuff's review here. This is someone who listened and took their time evaluating. Well done!
"But when it came to listening, there were some surprises in store. Straight out of the box, the 805s speakers were a substantial improvement on the N805 in every respect I can think of. Bass was not only more controlled, but also seemed to extend further. With or without the subwoofer, the improved 805s bass is of an upgrade-worthy level. I always felt a sub was a priority with the N805, but I can honestly say that might not be the case with the 805s. I don't know what the measurements show, but my ears tell me the sound from the 805s is more expansive and has more of a "wholeness" about it. The midrange has the same positive qualities I enjoyed with the N805, particularly with male voice, but I think any perceived change for the better in the midrange is really down to the better bass control which seems to improve everything else about the speaker. At the top end, the sibilance I noticed with the Signatures has vanished, and what sibilance there was with the N805 has been smoothed further. Yet the highs are not at all diluted. Listening to flute and female voice, I heard at least as much detail and extension as with the N805, but also a smoother, absolutely non-fatiguing sound. For me, this was a genuine, valuable improvement enough to make the upgrade essential."
