I have an old Sonos Connect that feeds into an old Onkyo receiver in my hearth room.  The receiver drives two sets of passive ceiling mounted speakers (through wall mounted resistor controls for volume).  Looks like my receiver is about to shoot craps so I am looking to replace it, but continue use of the old Connect I have in place.  Don’t want to upgrade as I have other rooms/old Sonos speakers set up throughout the house in different zones/groupings so just want an easy solution to replace my amp for the hearth room.  Would something like the WiiM Amp work for me (and perhaps offer some added benefit that I could stream other stuff through it to access my speakers)?  Or is there a better/easier solution?  Seems to me that it is a waste to buy a full blown receiver as all I need is an amp to drive my speakers.  Thanks for any advice!!!!
