Nautilus 805 setup question


Just got a pair of 805's and while fiddling around with placement, etc. I noticed that removing the grilles seems to improve clarity a little bit, but at the same time the speakers tend to reveal their position much easier; the soundstage is thus "distorted" left (speaker), right (speaker) and center become somehow "source points" instead of an evenly distributed soundstage in front of the listener. To make a long story short, the speakers don't "dissapear" so well anymore.
So is it grilles on or off? Similar experiences? any advice on tweaking/setup is also welcome.
Thanks

I love the sound of my Nautilus 805s, but they just don't image as well as I like. However, I hate making blanket statements about a single component like that without listing my setup. I'm sure there are other factors - it's called a sound system for a reason:

(4) B&W Nautilus 805s
(1) B&W HTM-2
Rotel RSP-1066
Rotel RMB-1095
Rotel RQ-970BX
Music Hall MMF-5
Denon DVD-2500
Home Depot speaker cables

I listened to some Vandersteens and fell in love. I'll always keep my 805s, but I'm already plotting my next system (with a 2-channel focus). The Vandersteens are in my site.
Nrenter,

I have owned both the Nautilus 805s and Vandersteen model 3.
I actually upgraded from the Vandersteens to B&W.
Bottom line? I think the 805s need a higher quality
front end to really show their stuff. The Vandersteens
are more forgiving.

Currently with my 805s I have
Krell amplification
Theshhold preamp
Electrocompaniet CD player
Discovery Speaker cables
Audioquest interconnect

The 805s VANISH. Completely and utterly.
Speaker placement does affect this. They have
to be widely enough separated. In my own listening
room I place them on the long axis. There is NO
sidewall interaction.
Judit,

Thanks for the reply (9 months late). I kinda forgot about this thread.
