B W Matrix 805s vs Nautilus 805s

Matrix series are warmer while the nautilus series are much more transparent, hence sound leaner. Its upto individual preferences. I'm using the matrix series and am mighty happy. Yes - I've been persuaded to changeover but have declined and it remains that till today! As I said, its your own individual listening preferences.

I've extensively a/b the Nautilus line when moonlighting in stereo sales at a high end audio store

I prefer the 805 with a good sub to the 803 and 804
You hear too much of the cabinet resonances in the 803 and 804 which are not present in the 805.

speaker placement is critical

The 802 seemed to have the best balance of all
The 801 was slow and imprecise. The bass frequencies sounded a little bloated

just my opinions based on my own ears

What about the Nautilus 804's. How are they?
