In Reply to: QSC Amps - Audiophile Quality?? posted by Greg Ewing on November 30, 2004 at 14:29:28:
QSC amps are designed to be highly accurate, with no deliberate coloration; that is, we intend that you get out of them what you put into them. That said, the RMX amps are our entry-level series, and the bias network in the output section is fairly simple, with an also simple temperature tracking scheme. In the PLX amps, for example, the bias network is much more complex and tracks temperature much more accurately, which makes the section much more linear, especially in the transition region where positive signal voltages cross zero and become negative and vice-versa, over all operating temperatures.Still, we're talking about improvements in very small non-linearities; in real-world situations you might never detect an audible difference except in a very well-controlled listening test.
The PLX amps and their derivative models also have extremely low noise floors, with hum components that are barely even measurable with test equipment, let alone audible. In fact, they would make good reference amps because of their accuracy and low noise.
