My only experience with a soundbar was at the local HifiKlubben store.
I do not recall the brand of the soundbar that was being demoed for another customer. I just noticed the night&day improvement when they shifted back to normal speakers afterwards.
Personally I have my Bravia connected to the second optical on my Caiman+.
