My audition was in a two channel system without subwoofer. The electronics were Mark Levinson and were kept the same for all three speaker model auditions.
In my friends system, the speakers are run full range and augmented by the REL. It would be difficult to estimate the differences when using an external crossover. I think it is important to consider the midrange driver and enclosure from the N802 is completely different and more sophisticated than that found in the 804/803.
If one were to have that much confidence in the subwoofers, would you not be able to get by with four 805's and not worry about floor standers? But since you already have the 804's, you should either stand pat or upgrade the fronts to the N802's if you can justify it financially. I do believe it would be a sonic upgrade.
