I have a pair of Paradigm on-wall Mini-Monitors, and I am looking for an amp or receiver to drive them that doesn't take up alot of space. Ideally, it should be less than 9 inches wide and 4 inches tall, but the smaller the better. The power should be in the 30 to 60 Watt range (into 8 ohms). The only control I need is volume adjustment. The input will be from a PC sound card, so all other audio adjustments can be made from the PC. Does such a device exist? I have Googled 'miniature stereo amplifier' and only came up with some piece of crap RCA that puts out like 5W. Thanks in advance oh wise A/V gurus.
