Ugh, I have a half-height Marantz A/V which struggles to drive my 5.1 B&W 600-series speakers. Since moving to my new home, where the couch doesn’t face the wall, I was inclined to ditch the set up and get Arc+Ones. It looks fantastic... but: - no DTS:X encoding. What? Many UHD blu-ray movies only come with DTS:X tracks and no, getting your player (e.g. XBOX One) to do the conversion doesn’t do the trick because for object-based audio formats (DTS:X and Atmos), it has to be done by the processor, which has data of where the speakers are. And I disagree the future of 4K movies is streaming (which favor Atmos, according to Sonos), because the difference of any streaming 4K movies and an UHD disk without all the ridiculous compression os night and day - this is not a problem exclusive to Sonos, but no brand does anything to help with cable management. Yes there are less wires with soundbars, but the rears are where the main problem is. With wireless rears, you’re just trading speaker wires for power wires (with the exception of one soundbar brand selling battery-powered rears, but forgot which now) So, with all that and considered the price, I couldn’t justify getting the Arc system.
