Frank,
I guess I should have included that info, Yes I was in the same room and used the same electronics for my audition of both the N804's and F30's. The characteristics I look for in a speaker are based on this. I graduated from a college with a nationally recognized Sound Recording Technology Program and I had several friends in that major and I had the pleasure of attending several sessions with them and got to listen to what THEY were looking for and I carried this over to my preference.
I should be able to close my eyes and hear EVERY aspect of the music...the hi-hat being hit, the drum brush rolling on the snare drum, the pick hitting the guitar strings etc. I want to FEEL the music...Am I "feeling" that bass drum like I was in the same room as the drummer??.....am I getting that "rush" from the guitar players amplifier?? The vocalist singing to me directly..etc. As a former drummer, the percussion (bass) section to me is most critical.
To me the Revel's did a better job at meeting this criteria. Did the F30's execute this perfectly?? NO! But did they do a better job then the N804's? Yes! Now regarding the Nautilus series, I have listened the whole line and they are great speakers except the N804's & their center channels..they just didn't do it for me!
The speaker I LOVE the most that meets all of that criteria is the B&W Matrix 801 (last series)...I LOVE those speakers!!!!! I would love to base a system around them!!!
Again this is my opinion..there are many people who will disagree with me like you, which is fine, it's not going to spoil my dinner!

..If everyone had the same taste there would only be 1 speaker out there. I just like to recommend options to people who may not have thought about a different product to research.
I hope this answered your questions.
Michael
p.s. I guess I should add this. I am only 29 years old and my taste of music is probably DRASTICALLY different then most of the members. I have a feeling I am one of the younger members here!

I prefer hard rock/progressive heavy metal, Big band, rock bands like Rush,Queensryche, Dream Theater, Metallica, Alice in Chains but I also respect Billy Joel, Elton John, Barenaked Ladies, Dave Matthews for their musicianship. I even get "Jiggy with it" if need be!..lol
