I have owned 8 pairs of speakers over the past 15-17 years. I have also heard over a hundred of speakers at dealers, friends’, and audio shows. Currently own 803 D3 and could not be happier with them. I kept going back the 800 series Diamonds, until I finally took the plunge I don’t regret.
Having said this, two important observations:
1) Speakers are highly personal. Get those YOU like. There are no one-size-fits-all speakers.
2) Components, and most importantly components matching, matter. A lot. They can make or break a speaker.
