If you're not handy with a soldering iron you might consider looking for demo boards for those IC's at Digikey or similar distributor.
The THAT 1580 is probably the easiest since it's 1 IC with all the preamp funcitons integrated, so lower number of external connections.
If you don't care about the amp being hi-fi you can do it with a simple op amp circuit, going from $5 per channel to <$1 per channel. Let me know if you want to see a schematic for a simple mic amplifier -- can be done with a 2-transistor package or an op amp.
This one can give ~26dB gain:
This is similar:
Those circuits are made for guitar input, designed to clip gracefully (comparatively soft clipping) rather than driving the ADC to digital clipping. For voice and microphones it is also likely to be a desirable feature. The only down-side is these weren't designed for tons of gain, but this can be changed easily enough if there is any interest in one of these circuits.
For low noise operation a mic preamp IC will be the best choice, especially if looking for low parts-count compact board.
