Power amps bring life to your passive studio monitors and live sound loudspeakers. Active speakers with integral amplifiers are indeed convenient, but having a separate amplifier will generally yield better overall sound quality and allows for a modular approach in live sound settings, letting you choose how much power you need for a particular venue. Reverb has a huge selection of new, used and vintage power amps from all leading manufacturers and in virtually all power and impedance ratings, so confirm what you need for your speakers and find the best deals on power amps for your system.
