Hello, I found a nice little compression driver that I want to use as a talk box. It is rated for 80 watts RMS. I'm planning to connect a nerd-kit to the D/A converter, to generate the sound, but that won't be nearly enough to drive the compression driver.

So I wanted to get some advice, weather I should design a Class B (or AB) power amp, or just try to find some pre-made amplifier.

What would be cheaper? I plan to use wall-power (USA, 110Vrms) to get amplification, are there some cheap pre-made amps that run of the wall-power?
