Hey all,

Apologies if this has been asked before or it isn't the right place but I can't find an up to date answer for what I am looking for so I am hoping someone may be able to help me :)

A while ago I bought a load of Nest Audios, Google Homes and Chromecast Audios to rig up in the house and in the garage to a receiver that runs two sets of outdoor speakers.

Overall, the system works really well and allows the devices to be grouped into multiple groups which can seemlessly play audio without delays. My only gripe with it is that if the internet goes out then due to the way Chromecast stuff works you can't cast to the groups and all the devices disconnect from the WiFi even though most media we stream to the is local from an Emby server.

Recently I've been thinking about expanding them however I would like to move towards a system that supports a "fully local" setup as whilst our internet doesn't go off often it's kind of annoying that it kills the home audio if/when it does.

Likewise Chromecast Audios were discontinued a while ago and getting a hold of the left over ones means paying 4-6x the price they were sold at for something which Google might decide to bin off in a few years time.

I've had a look at a few systems such as Sonos, WiiM etc but all seem to have pros/cons that are less balanced than the used CCAs. Ideally I would like to have a system that can work with the following:
  • Stream audio from phones/PCs
  • Stream from Emby or SMB shares
  • Support multiple audio groups
  • Be able to connect to a seperate amp/receiver/speakers
  • Possibly have their own speakers (For smaller rooms)
  • Connect to Home Assistant to manage volume levels
So far I have found the following options:
  • WiiM - Works similar to CCA and supports casting however unsure if this will have the same issue of needing to be online all the time, fairly pricey but not obtusely expensive, unsure how volume levels are managed
  • Wired speakers - Seems to be the most agnostic solution since you can just swap out the central receiver but a massive pain in the butt to run cables to all ends of the house, relies on having decent seperate speakers and a central app, also unsure on how volume levels would be managed remotely
  • Sonos - Has its own casting system and doesn't support Google Cast, can use receiver units or IKEA/Sonos speakers, can work offline, quite expensive but the most well known, eco system which is pretty locked down
  • Snapcast - Uses Raspberri Pi and some addon boards, vendor agnositc and just needs connecting to a seperate amp, looks to be the cheaper of the options but potentially very faffy to setup and maintain
Anyone who has had similar ideas before or setups I'd be interested to know your thoughts and what you ended up doing :)
 
There's Wiim amp, you then add stereo speakers. Or if you don't want the amp, wiim pro plus or ultra when it's out. You have a fairly specific use of audio. They will stream from your NAS server no problem.

Wiim Pro Plus has BT receiver so you can transmit from your phone to the PP

I just use Squeezeboxes with Pi5 as a LMS server, that works well. Plus with Softsqueeze it's one I'd get .

I wouldn't touch Sonos.

For each room need to decide what audio system you want. Single active speaker? Ceiling speaker? Bookshelf passive speakers? Small sub/sat system? Bookshelf active speakers? Hifi? Home theatre? etc.
Thank you for the info :)

Generally speaking the rooms will be:

3x Single active speaker
1x Hi-Fi or Bookshelf active speakers
2x Hi-Fi/Outdoor Amp (Outdoor speakers connected to amps)

The WiiM amps look good but definitely pricey

For the RPis and Squeeze how do you have it setup, do you have it behind an amp etc? :)
 
You could get three Wiim minis for the active speakers, Velcro stick them to the back of the speaker hidden away and have a decent streamer/active speaker
For Hifi if you are using analogue out of the media player, get pro plus or ultra
You'd be looking for weatherproof speakers, and suitable cabling for outdoors use

Need to figure what for Hifi, budget, speaker brand and type etc.

Wiim amp has built in subwoofer integration, high pass so for a 2.1 system it's pretty good, and for the price it's a bargain. It's not pricey haha. Wiims will be getting room EQ in the future, and they even have PEQ so get a lot for your money.

Raspberry Pi5 has pircoreplayer installed that has LMS (that's a music database scanner) Music on my NAS, and each room has Squeezebox Touch/classic/radio
I see :)

You are right, it looks like I need to see what speakers I want as this could get pricey haha, I like the idea of the minis on the back of the active speakers then the pro units for inside the garage.

I guess the search is on for decent speakers now as for the single rooms I'm trying to keep it to under £100ish but I might have to up that for decent ones :)
 
Decent speakers cost more than £100. You're not going to get anything under £100 they'll be speaker shaped objects.

I'd say something like a acoustics 3020i or wharfedale diamond 9.1 that sort of thing as a starter budget speaker. For main room want a sub with those standmounts plus stands. Standmounts might not provide enough bass in a larger room. Speaker and RCA cable. Coaxial/optical cable from wiim to your amp if it has that connection otherwise be stereo RCA.

Good towers somewhere close to £1000. I'd avoid cheap towers, instead get standmounts as you'll get better quality for your money.

I'd set aside a couple of thousand for your whole system..
Rather than expect to get everything for contents of a Yorkshire man's wallet
It looks like this is going to be a long project but you are right it looks like if I want something that sounds decent I'll have to save up for it!

The 3020i units look decent so I might start with a pair of them and see how they sound. :)
