AudioSource makes some inexpensive amps that are great for zone 2 or 3. They have refurbs on Ubid occasionally for as low as $50-60.
...I've got an Audiosource Amp One/A powering my zone two from a Denon 2805, it sounds fine for background music. I havent had any issues with volume and the price was right, $65 for a refurbished unit from uBid.
My friend put an Amp One in her place ($60 @ uBid), the one unit is powering both her kitchen and bathroom, and she is completley happy with it. Plus they are stable to 2 Ohms.
Most dont recommend these for "serious" listening, but for a second zone and background music the price and performance on the refurbished units is hard to beat. They pop up at uBid every couple of weeks for the Amp One and every 3-6 months for the Amp One/A.
