Please make a sonos multi zone amp!

Actually either or will work. Both have an input so you can add a chromecast audio $40 dongle to either and you will have full chromecast ability. Awesome! So I just need a connect:amp and another chromecast. Thanks everyone!

Sorry, but I was looking at the Connect:Amp page and it doesn't look like there's a USB port to plug in the Chromecast: http://www.sonos.com/en-ca/shop/connectamp

The new chromecast audio doesn't use USB. I have one connected currently to my play:5 (which has same 3.5mm input as the connect:amp). https://store.google.com/product/chromecast_audio?utm_source=en-ha-na-us-sem&utm_medium=desktop&utm_content=plas&utm_campaign=Chromecastaudio?gl=us&gclid=Cj0KEQiA4LCyBRCY0N7Oy-mSgNIBEiQAyg39tuoHp10ovS0Qt57jPGWICzDagZuheHKkPA6sIC12NAEaApHx8P8HAQ

The Connect:AMP has Auto-detecting analog (RCA) line-in connections.

The Chromecast video has only an HDMI out.

The Chromecast audio supports RCA, 3.5mm, and optical.

Man, that's cool! I've got a chromecast video and assumed that was it. That is a pretty sweet setup! I can't wait to get my connect:amp now!

Why is it that Sonos thinks everyone wants tech clutter in every room?
Yea, people accept it if they have no choice, but any new house these days gets built prewired with cat6 and speakers in the ceiling and nearly every "remodel to the studs" project as well.

So why wouldn't Sonia think that is a big enough market for them? Obviously Verizon thinks it's big enough with its FIOS fiber optic system (which is a way bigger investment than Sonos putting together a multi zone amp. If anything they should at least make the amps stackable.

5 years from now most houses will have a tech closet with a rack of stackable tech equipment. Having the equivalent of a 90's style network for sound equipment seems pretty ridiculous these days. Anyone remember when DIRECTV required an individual satalite dish for every concurrent tv wanting to watch a separate channel? They don't do that any more, lol!

If I want to have music in half a dozen rooms/outside do I really want 6 non stacking pieces of equipment (in an earthquake zone) on top of all my other IoT systems.

Everyone's response is that this is what Sonos has done for years. It's pretty obvious that they've been doing it this way for 5 years too long!

The Sonos response to this question seems to be that for such a situation, the play units are its solution.
For sound quality, they will always trump ceiling speakers. And the only place where current model play units can't work is in shower cubicles or outdoors; third party speakers driven by Connect Amp is the solution for these.
The market for cases where these Sonos solutions are not appropriate may be one that Sonos isn't targeting at this time.

I don't think people really want tech lying all over the house, especially in places like bathrooms.
The equipment attracts dust, meddling kids, water, etc (I.e just waiting for stuff to happen).

People who buy new places or are willing to remodel their house don't want the equipment cluttering every room in their house.

Sonos might think that their typical "customer" is an audiophile who doesn't mind the tech clutter, but what they don't realize is that most of these customers are married to those who are not down with having tech clutter residing outside the "man cave" lol.
And now all that clutter is scattered All. Around. The. House!

How is a play unit, wired to the mains socket in a room, clutter?

Don't see that at all.... They won't be 'audiophiles' and Sonos kit is generally used to reduce clutter - not create it...
