Default Amps for Whole House Audio : Multi-Room : Muilt-Zone

I'm going to be setting up a system to pipe audio into all my rooms in my house and my patio - 4 separate zones

I will be controlling everything separately via a PC so each zone can have different music playing.

Since these are mid-level ceiling speakers for 'background' music the amps don't need to be powerful but I'd like them to be decently clean/clear.

I'd like to use a digital amp due to size and power requirements. Just wondering if anyone has done this with a T-amp or any of the DIY kits... what you used, what case you used, how it turned out, etc.

Thanks for the tips/suggestions!

Multiple T-amps right at each speaker would be great for such a system. Just make sure to use shielded signal wiring, and possibly some differential line driver and receiver circuitry, to help avoid noise if you go that route.

I can recommend the Sure Electronics TA2024 T-Amps, for $25 delivered.

ebay.com

They run well from 12v SMPS, but I advise that you at least remove the 2 unnecessary input capacitors if you want them to sound really nice.

You can have a look at www.xlobby.com (there is a freeware version, have a look in the forums). With a bit of ******** around you can setup 4 separate zones with separate control (look for kx drivers thread). I haven't done it myself so I can't remember if it is multi-source. Cheers, cc&c.

XLobby is what I'm planning to use... BUT development on it is SLOW and I'm loosing patience. I'm starting to look at Girder5 & Netremote

Currently I use XBMC (on the original xbox) and it is being ported to Linux. So, I'm hoping that will be a viable solution once it reaches its first release... and it is free.
