I just bought a A-bus hub for the house. It seems pretty staight forward but I was wondering if any of you guys have used or installed one of these in your home.

What am I getting into?
How is the sound?
What kind of speaker should I use?
Buy premade cat 5 or make my own?

Any other things to consider?

No room in the house needs to be without music with the ABH 4 around. The ABH 4 from Harman Kardon allows you to power up to four rooms off of this one A-BUS expansion hub. For systems without an A-BUS ready jack, the ABH 4’s onboard audio inputs add the simplicity of A-BUS technology to most stereo receivers.

With abus you are limited to an amplifier in a keypad. So I guess it depnds on whether you like to play your music loud or if its just for background.
