1. You're thinking volts. Amps is the amount of current the supply can provide. The Squeezebox will only draw as much current as it needs. The power supply must be able to provide the minimum amp requirement. If it can provide more amps, then that doesn't hurt anything. For linear power supplies, voltage regulation is usually better if the current draw isn't near the maximum the supply can provide. 2. The "wall wart" power supply for the Squeezebox 3 (i.e. "Classic") emitted a lot of high-frequency electrical noise, both back into the power line and as radio waves. This can interfere with some systems. A linear power supply emits very little noise. Reportedly, the power supply provided with the upcoming Squeezebox Touch is much better with regards to unwanted noise.
