Would u give up usher mini dancer 2 for b&w 802's

Absolutely no for me.
Though a bit nasal and bloated in the mid bass the ushers are drivable and has that very smooth yet transparent mid to extreme high.
In comparison the 802 sounds very incoherent.

I'd give up audio if I had to put another pair of 802's in my system.

I really do not like b&w speakers in general.

You're in a lose-lose predicament.

As a previous Usher dealer, I would not change the Dancer's for the 802, The Dancer's are very, very, good speakers.

I would give them up for the new Janszen ZA 2.1 electrostatic hybrids, I have been doing this professionally for over 25 years, and I can't remember ever hearing a loudspeaker which is as intoxicating as the Janszen.

The Janszen is unlike any electrostatic speaker on the market they are compact, relatively efficient, easy to drive, they play loud, have excellent deep bass and will work in any room and in any part of the room.

The midrange performance of the Janszen is remarkable with a clarity in the midrange that is spooky.

So in summation Dancer 2 to 802 not enough of a difference, Dancer 2 to Janszen yes, yes, yes.
