Why do you think the Sonos ZP90 costs as much as it does? Isn't it essentially just the Sonos network capability with a DAC and a couple of outs? When you think the Play:3 has much of that + amp and speakers for a similar cost, is there a sense in which the XP90 is priced oddly? Especially since the DAC in the 90 isn't supposed to be the best.
