Don't use a Play1. Older people who don't understand tech will now think about Sonos as a bunch of Play1's around the house. Use a Connect, your amp of choice, DAC, and a GOOD pair of bookshelfs. Let them experience something good and tell them that on the permanent install the equipment will be hidden and the speakers can be installed in the wall or ceiling. When doing demos always show them what is possible and then let work back to the price they want to pay. Never demo junk.
