I had a surround setup when they first came out, prior to B&O. It was difficult to wire the rear speakers, and then I barely used them because often the little ones were asleep. I haven’t bothered with surround sound since.
Adding wisa rear speakers to my Eclipse is on my list, but I have a hard time justifying the cost of bl17s when I’m fully satisfied right now. Although, it sometimes bothers me that I’m not using the eclipse to its full potential.
Honestly, I’m very happy with the sound performance of the Eclipse without any external speakers. I have a bs2 connected, but only turn it on for action/adventure movies. 90% of the time the sound center is all I need/want.
I think there is a market dynamic here that is similar to the growth of “single point” speakers where convenience tops sound quality. At least that’s how it is working for me right now.
