Sonos Amp with Bowers and Wilkins 685 S2, my Sonos Play Ones sounding as good?

So I have a Sonos amp with BW 685 S2 bookshelf speakers. I’m finding the other speakers in my Sonos group, play ones and 1s, in stereo pair are sounding full and sometimes better than the 685s.

Now, I know the 685 S2 are great speakers and should be worlds better, but why am I underwhelmed? Is there something I may have setup incorrectly? I have them with 4 bi wire cables on the speaker, with 2 on the amp end with banana plugs. They don’t sound bad, just a bit underwhelming especially compared to the Sonos ones

Sometimes I think getting rid of them and just having a Sonos 5 in their place would round out my speaker and music much better


So you understand my set up better, here is how I have it in the same room:

Group 1: 5.1 beam, sub, and two play 1s
Group 2: two Ones on the sides
Group 3: two BW 685 S2 with amp in the middle


For movies obviously I use just group one, but when listening to music I like to group them all together for a surround affect. I added the 685s because the center sound was lacking from the beam in music especially when all speakers set to full.


Any ideas?
