I am looking to upgrade a pair of Sonos Play 1s currently operating as a stereo pair in my lounge. My options seem to be either changing them out for a pair of Sonos Play 5s or using a Sonos Connect Amp ( which I already have) and buying something like a pair of Kef LS 50s. Cost will be about the same but I cannot find a local retailer where I can listen to the options. Anyone out there who can provide advice and help?
