General Asylum: REVIEW: QSC PLX 3402 Amplifier (SS) by The Defiler

audioasylum.com

The QSC PLX 3402 amplifier impresses with its massive 3400-watt power, offering remarkable dynamic output and detail, making small speakers sound far larger. While it boasts less fan noise than its RMX 1450 counterpart, it may still be too "solid state" harsh for some tastes. It lacks the warmth of high-end units but compensates with its portable design and affordability. Ideal for those seeking raw power and clarity.
