To pricey

This has become so typical of posters here, most detractors never even heard the speakers or brands they often criticize in their home. Those complaining about B&W being bright and so on, please tell me which speaker doesn’t require careful matching with upstream electronics to sound its very best……

@lalitk i had heard them, in my home. I didn't like them. Other people love them. That's exactly how it works, we find that there is no ultimate list, we all have different favorites. 

1. Buy used.  2. I like the 803 D3. You may not. Others here express their love and dislike of b&w. They’re all correct. Now it’s your turn to decide.

Most here, in this thread, have.

Good point, but-

It`s either you move on to a more satisfying speaker, or you spend more money on the components, upstream, to match them. I did this. I have a SS amp paired with a tubed preamp. My B&W`s don`t sound bright, as they once had, but wonderful.

I own the 804 D4 and power them with a Gryphon Diablo 300 using Transparent cabling, my source is a Lumin P1 and sometimes I go USB out via a Lampizator Baltic 3 DAC. I bought the speakers/amp/source and cabling from the same dealer where I auditioned multiple system combinations from the likes of McIntosh Classe Sonus Faber Totem Aurender etc. I agree with those above who said your amp won’t produce the sonic goods with ANY of the 800 D4 series speakers. I would stick with your Nautilus speakers and upgrade your amp OR if you really have specifically speaker upgraditis you might want to try the Spendor D series for a more neutral/warmer sonic character or stick with a more high resolution brand like Focal Kanta series that are easier to drive than B&W.
