Simple, Cost-Effective, Multiroom Audio?
jimicus writes "I'd like a multiroom audio system but I'm thoroughly confused by the options available — and the difference in prices is huge. For instance, Philips have a wireless system which starts at around £280 — and Russound have a product which comes in around £1,000. I've already got all my music as MP3s and it lives on a NAS box — I don't really want to repeat that process. I also have a perfectly capable amp and speakers in my living room, so I don't really need anything else there. Whatever I go for has to pass the wife test — so something which requires a separate amp, speakers and PC in each room and requires a keyboard to control is right out. I don't mind spending a little money but I don't really want to find that every little extra thing adds up to £thousands. Has anyone else dealt with a similar problem? How did you solve it?"
Any internet connected machine will control the audio programming, and any old FM-radio will do the trick of receiving the signal. Simple. Effective. _AND_ Wife-Friendly(TM) (at least, according to my wife ;)
Because of FM-modulation, this technique is not hi-fi. But a decent transmitter does an admirable job in retaining audio quality.

C Crane sells an FM broadcaster which has a variable potentiometer which can be easily adjusted to boost the range beyond what the FCC allows.
If you attach this to your NAS as an audio output or your main stereo, you can relay what you're listening to in nice FM stereo throughout most of a large size house (goes well through my 3-story house and even our detached garage).
FM broadcast is cheap, it's easy to add new devices that are easy to use, and the music is perfectly in sync.
If you're broadcasting from a NAS, add a usb sound card to broadcast the music, and control it with MPD, which will allow you to change music via a lot of clients, including an iphone.
I second this. If you're already using iTunes, it's a no brainer. They're cheap ($100 new, ~$60 on eBay), contains all the networking stuff inside the box. I connect them to small powered speakers in the remote rooms (Klipsch ProMedia 2.1) and it just works. I've had Crestron and Control4 stuff before for TONS of money, and it just always seemed like overkill for my needs.
The Rocketboost system at best buy is a wireless solution that will work for you: http://www.bestbuy.com/rocketboost gives a good summary of how it works.
You can add speakers and audio sources around your house, and the speakers have a "next source" button that lets you flip between your audio sources. It is modular, where you can buy as many units as you need and they all join together into one big network in your house. It isn't super-cheap, but it is cheaper than other products that are equally as flexible in how you set them up.
Disclaimer: I worked on this product (wrote the protocol stack for moving the audio data over the air), so you may want to take my recommendation with a grain of salt, but I am happy with how well the product turned out and I think it's pretty neat.
You want a "distribution amplifier". These usually downmix to mono (seriously - You want mono for this purpose. Stereo coming at you from several direction at unbalanced distances will get annoying fast), and have a large number of channels (12-16 would work well for most houses, unless you really need it in every corner of every room including the attic, basement, and garage).
They don't cost all that much, which leaves you to spend your money on decent speakers. Depending on your home layout, you may want surface-mount, or recessed, or just cube-in-the-corner. As for wires - Keep in mind you either have signal, or power, or both going to them. So wireless doesn't really buy you all that much unless you absolutely positively cannot make discrete 1/8" holes hidden in the corner/wall/floor/ceiling/whatever. Personally, I consider speaker-wire easier to hide than power, so have chosen to just run an array of speaker wire through the basement up through small holes between the floorboards (old-style New England house with a decent gap between floorboards, so as close to invisible holes as you could ever want).
But yeah, you don't want a high-tech solution, you want an old-school distro amp. What you feed it with depends on what the wife will put up with, but you can find a huge number of digital car audio solutions that provide minimalist interfaces with decent functionality.
I have 3 airport express', one in the bedroom, one in the dining room, and the other in the kitchen. They all work wonderfully and it has replaced our stereo to the point where we simply don't use anything else. That was great, but the thing that kicked it into overdrive was the remote control app; with the iphone or ipod touch, I can control everything wherever I am. Absolutely brilliant setup!
I assume there are other setups like this, but I don't know of them.
I don't get why all you people are suggesting computer-based solutions.
Running wires to each room in the house would be both cheaper and have sound quality independent of network quality.
