B&W N803 or Signature 805?


This is my 2nd posting as my first somehow didn't come out.

I am well aware that this is an unfair comparison with the N803 being a floorstand and the S805 as a standmound. However, if given the opportunity, which would you choose? I am looking to upgrade my Sonus Faber Grand Pianos to either one of the two mentioned as I preferred the B&W house sound more than the former.

I would be most grateful if anyone who had heard both speakers would chime in and give your opinions. I currently have deals on both speakers and a purchase would be imminent.

The Tweeter of the Signature is a lot better than the one of the N803. Is is more detailled and less harsh. But the 803N goes a lot deeper in the low freq. So it depends what you are looking for. Maybe an 804S is a better solution.
For me it's realy hard to imagin how to outperform Grand Pianos with B&W N803 or S805, but in comparison between N803 and 805 I liked better the monitors. Monitors beat with presentation, tightness and imaging.
Thanks for responses. To put in another way, I preferred the B&W sound more than Sonus Fabers. I have owned the N805 and liked them much more than the Grand Pianos which are too warm for my listening preferences with a rolled off high frequency/treble.

The N805 is not too bad but was hoping to get more transparency, detail and dynamics with either both speakers mentioned.

Cheers.
