After lots of deliberations, finally gave up to the better half to go wireless. Spent half day cleaning the rear of the TV stand and disconnecting the wires (wow the place now clean).
Connecting the Sonos ARC/Sub/ERA100 was a breeze (not to mention their fine packaging). Tuned the speakers with Sonos Trueplay. Initial excitement has now passed. Really enjoying the Sonos for movies. I didn't have a proper HT set-up i.e the floors, center and surrounds were different brands.
For music, I may be criticised. however, I found the yami 3070 was much much better. The Sonos is super easy to play. Going to have coupe of friends at home today... will provide more impressions soon.
