B/W 702 s3

Having owned a Rotel amp and being familiar with the B&W signature sound, there may be a synergy issue. My Rotel tended to be on the bright side and most of the B&W's I've listened to seem to be a bit bright as well. Some of the others who posted suggested a sub and I also think that will help. Despite being a bit bright, B&W's are also very revealing and provide excellent soundstages and detail. If I was to switch anything out, it would be the amp. 

I have a pair of Fyne F-72s with 8" woofers, and they were lacking in punch at the low end.  Still are, but I added two Rythmik FS12e subs, and that made a HUGE difference in the sound, even beyond the lower bass register; it was a definite transformation.  I am not familiar with the Rotel line, but I am driving my Fynes with two Odyssey Kismet mono blocs--which I will soon have converted to stereo to vertically bi-amp the speakers, and the sound quality is superb ... again, with the two subs.

Thank you all for your great comments and advice.  Let me tinker with placement.  They are toed in a bit.  Clearly my room is not ideal.   Very open and the entire right side is glass windows.  Tried to load a picture and can't get it to post.  The 702 s3's are ported downward and not out the back, I am not sure that is an issue. I am not sure the Rotel gear is all that great, I am kind of deep into the Rotel gear and would hate to move on at this point.  

As for adding a sub or two, would you recommend mono or stereo subs.  I do have a mono sub jack on the Rotel RC 1590 MII

Again, thank you all-great stuff!

I  do not think a sub will be an improvement unless you want next level dominating bass.

Sometimes a better amp is the solution, but also look at your room. If it's pretty reflective some damping will reduce the mid/treble and let the bass bloom.
