Tunksy31, no offence, but you're contradicting yourself. In post #3, you inferred the sound quality isn't optimal with these analogue systems, yet in post #8, you think I'd be amazed if I spent enough on speakers?
If I'm going to the trouble of spending $$$ on speakers, then I'd want them to be reproducing a clean signal, not something passed through 100ft of cable snaked around the house, picking up AC hum, other noise artifacts and the audio effects of impedance imbalances from long, unequal lengths of speaker wire.
I'll bet dollars to donuts that my FLAC->SqueezeBox->Adcom setup (or
any source for that matter) delivers cleaner, more accurate, richer sound over matching 10'
12awg cables, into a pair of Celestion speakers in my living room, than would be the case if I extended those cables ten-fold, snaked them around my house and placed the speakers in a remote room.
Let's say for arguments sake that you're driving 100W into an 8R speaker. That pegs the voltage at ~12V and current at ~8A. Driving an 8A load, your 14awg speaker wire is losing >2V per 100' and that voltage drop increases with power/current (

So, over 100' of 14awg of cable,
you're losing 12/2 = 16% of the voltage you're trying to drive into the speaker from resistance, before capacitive loading similarly destroys your AC signal.
So, how's that sound quality working out?
Also, in comparing w/ Sonos, you're taking the $$$$ end of the scale. The reality is that you can setup a comparable system using SqueezeBox for as little as US$200 per zone. Through a combination of wired/wireless Ethernet, I have 5 music and 2 HD video zones served from a 10TB digital media server.
Excluding the Adcom/Celestion gear that I already had, the whole-home music system cost me ~$1,200 for all 5 zones (a $400 Duet and four $200 BOOMs). Extending the system to provide HD video was a simple matter of adding a pair of $100 STBs and Ethernet cable. Try doing that w/ analogue wiring!
Multi-room analogue systems
were attractive and are still somewhat popular, but the transition from analogue (physical) to digital media and the explosive growth of home networking will quickly render these systems obsolete like the other analogue technical marvels that preceded them.
While 100's of feet of speaker wire may be considered
by some to be a great selling feature today, anyone wishing to 'wire' a house for entertainment/information would be best advised to run high-quality Ethernet cable. That will be a much more attractive selling feature of a house in the near future; more so than the scrap value of a few hundred feet of 14awg copper wire, anyway.
