I have similar music taste and use So What as one of my benchmark tracks when evaluating speakers.

I liked the B&W T7. It sounds really good for what it is. The sound is very neutral and detailed and it doesn't try to do anything it can't. It is very much what I have come to expect from B&W. That being said, I think you would like this unit.

The HK Aura and a few other wireless units from Harman all sounded really bass heavy to me. This is very appealing to kids and people who want to listen to hip-hop, but not me. The bass at the beginning of So What is so forward that it is distracting from the piano.

I have not heard the B&O unit and honestly, haven't demo'd a B&O system in about 15 years. I have no POV.

Dynaudio makes some excellent wireless speakers, but they are more expensive.
