Today I briefly thought this Class T Amplifier would yet me put assemble a two-room speaker solution with an iPod/AirPort Extreme input in a very confined space. Alas, some native suspicion and a very persuasive negative Amazon review led me to investigate an alternative that appeared on Amazon's 'what people bought instead' list.
I ended up ordering the AudioSource Amp 100 2-Channel Power Amplifier from Amazon. There was one review, and the reviewer was looking for the same thing as me. This amplifier is only 8"-9.25" deep (numbers vary) and it accepts two inputs and sends output to A/B speakers. It even has a volume control. Very simple. $140. Seems just right. My only worry is the depth. We'll see!
Now I have to buy the AirPort Extreme (after the 10/12 Apple product announcement) and two pairs of speaksers -- bookshelf and mounted.
