I think a better smart amplifier could be a good product -- and then people can bring their own speakers. Or you can make great wireless speakers and then people can bring their own amplifier. But the moment the speakers and amp become an 'integrated solution' I hear the e-waste bells toll in the distance.
People have been burned by sonos and don't expect their framework laptop to last more than a couple of years. Meanwhile my 25 year old dumb speakers are still going strong.
